Statistics Canada unfounded change drives up crime numbers in Surrey BC

first_imgSURREY, B.C. — Mounties say a significant increase in violent crime in the first quarter of 2019 in Surrey, B.C., is partly due to a new Statistics Canada reporting requirement, and the change is likely to affect police data across the country.The federal agency announced revisions to its Uniform Crime Reporting Survey last year, following national media attention and police reviews of the use of the “unfounded” designation for sexual assaults.The changes took effect Jan. 1 and mean that “founded” occurrences now include offences where there may be no evidence to substantiate that an incident took place, but there is also no credible evidence to confirm it didn’t happen.Previously, offences that could not be substantiated with evidence were not included in a city’s crime statistics.Surrey RCMP say it’s too early to fully assess the impact of the changes on crime statistics, but its analysis shows that some crime types are impacted more than others including assaults, uttering threats and shoplifting.In the first quarter of 2019, total Criminal Code offences increased four per cent in Surrey compared with the first quarter of 2018, while violent crime jumped 43 per cent with notable increases in robberies, sexual offences and assaults.The large Metro Vancouver municipality appears to be among the first jurisdictions to release first-quarter statistics for 2019. Not all police departments release detailed quarterly numbers, says Surrey RCMP Cpl. Elenore Sturko.She says Mounties are taking a hard look at the data. Some of it is not attributable to the data-collection change — for example, a 48 per cent increase in robberies reflects a genuine theft spike that occurred in the city earlier this year.“We don’t want to completely write off everything and just say, ‘Oh, don’t worry about it. It’s because of the change,’ ” she says.“Violent crime in Surrey is something that is a priority and is remaining a priority for us. But understandably, some of this is as a result of the (Uniform Crime Reporting Survey) changes.”Sexual offences jumped by 48 per cent in the first quarter of 2019 compared with the same time period last year, while assaults increased 40 per cent.It’s difficult to say exactly what portion of the violent crime jump was caused by the Statistics Canada change and it’s going to be hard to directly compare 2019 data with previous years, she adds.Surrey RCMP “fully support” the change, Sturko stresses.“The reasoning behind making this change is a really important one, I think. It’s giving statistics that are more victim-centred,” she says.“Hopefully, as a result of these important changes, we’ll be able to eliminate the under-reporting of these serious crime types.”Statistics Canada has said that a victim-centred approach to recording crimes is emerging. The approach puts forth that, unless there is concrete evidence to prove the crime did not happen, it should be believed that the crime occurred.The statistics agency likely won’t release the Canada-wide 2019 crime data until spring 2020, says Robert Gordon, a Simon Fraser University criminology professor. It will be impossible to compare it to previous years, he says.“Basically, the clock stopped Dec. 31 and it restarted under a new reporting and categorization regime Jan. 1,” Gordon says.He says the changes reflect a major revision to the way police forces count crimes. Sexual assault and family violence have long been considered to be under-reported, and this change aims to address that, he says.For example, a complainant who tells police they were assaulted but refuses to proceed with the investigation will now be included in the crime numbers, as will a third party who reports child abuse but the child can’t or won’t report the crime, he says.“All these things where the victim says, ‘Ah, I don’t want to bother,’ you should still be recording them because they are actually crime incidents. It’s important to keep an account of those.”The change moves Canadians closer to understanding the extent of crime in our communities, but there is still an unknown number of offences out there that never get reported to police, he notes.“This new approach won’t change that one bit.”The Canadian Presslast_img read more

Yeddyurappa predicts defeat of senior Congress leaders in Karnataka in LS polls

first_imgBengaluru: State BJP chief B S Yeddyurappa Friday predicted the defeat of top leaders of the ruling Congress-JD(S) alliance, including former Prime Minister H D Deve Gowda, senior Congress leaders Veerappa Moily and Mallikarjun Kharge in the Lok Sabha polls. Signalling possible political instability in the state after the Lok Sabha poll results, the former Chief Minister said differences between Congress and JD(S) wouldincrease after the results are out on May 23. Also Read – Uddhav bats for ‘Sena CM’ “I have been saying this with confidence that we will win more than 300 seats across the country this time. InKarnataka, we will win at least 22 (out of 28) Lok Sabha seats. I’m saying this with confidence,” Yeddyurappa said. Addressing party MLAs, MPs and leaders meeting in the backdrop of bypolls to Chincholi and Kundgol assemblyseats on May 19, he said “the atmosphere is in our favour to an extent that Veerappa Moily has already lost against our candidate; in Kolar also K H Muniyappa will lose against our candidate Muniswamy.” Also Read – Farooq demands unconditional release of all detainees in J&K “According to our calculations, Mallikarjun Kharge will lose against our candidate 100 per cent, and in Tumkur the situation is that you will not be surprised if Deve Gowda is defeated. This is what we are hearing, I’m not saying this forthe media or to satisfy you, this is based on information we have gathered,” he added. While JD(S) patriarch Gowda is pitted against BJP’s Basavaraj in Tumkur, Congress leader and former chief Minister Moily is fighting a tough battle against BJP’s Bachche Gowda in Chikkaballapur. Congress leader in the Lok Sabha Mallikarjun Kharge is fighting Umesh Jadhav of BJP in Gulbarga, and in Kolarformer Union Minister K H Muniyappa of Congress is pittedagainst Muniswamy of the saffron party. Claiming that stalwarts of the Congress-JD(S)coalition wouldface defeat in this election, Yeddyurappa said the internal rift between the partners has once againstarted, and after the poll results are out thesituation would worsen. “In such a situation, by-elections for Chincholi and Kundgol have also come, which we will have to win hundred per cent,” he said, adding that names of candidates have been recommended to the party high command and would be finalised and announced by tomorrow. The outcome of the by-polls, along with the Lok Sabha results, is crucial for the ruling Congress-JD(S) alliance as it would have a bearing on the longevity of the coalition government, triggering the numbers game in the assembly. The by-poll to Chincholi was necessitated as Umesh Jadhavquit as Congress MLA and joined BJP to contest the Lok Sabha pollsfrom Gulbarga, while Kundgol seat fell vacant following thedeath of MLA and Minister C S Shivalli.last_img read more

Competition Council: Capping Fuel Prices Useless, Bad for Stakeholders

By Ayoub DerrazaRabat – In response to the Competition Council’s statement that capping fuel prices would hurt Moroccan oil market, the minister of public affairs and governance, Lahcen Daoudi, tweeted today that his ministry will proceed with its decision to cap fuel prices.The move will be made in coordination with various industry stakeholders, according to Daoudi.Unnecessary and harmfulCompetition Council President Driss Guerraoui said earlier today that the government’s decision to cap fuel prices was unnecessary and would harm industry stakeholders.Guerraoui told a press conference that the decision to cap up prices was “a real danger that could harm the small and medium-size stakeholders, making them more vulnerable.”Not only will the government’s choice to cap prices not be sufficient from an economic and competitive point of view, Guerraoui argued, but it would also be harmful from a social justice perspective. The measure can be applied to all stakeholders, regardless of their size and capacity, the council said in its opinion, which was approved on Thursday at its plenary session.We’ve been here beforeGuerraoui noted that this measure was already tested between December 2014 and December 2015 without achieving the expected results.He attributed the first failed attempt to the fact that stakeholders “generally adopt the fixed maximum prices without any effort to reduce them.”Guerraoui noted that the government’s request “did not meet the legal requirements of the Law on Freedom of Prices and Competition, which requires provisional measures aimed at temporarily excluding a product or service from free prices.”According to Article 4 of the Law on Freedom of Prices and Competition, the administration may “take temporary measures against excessive price increases or decreases caused by exceptional, catastrophic or manifestly unusual market conditions in a sector,” after consulting the Competition Council.Read Also: Morocco’s Fuel Prices Down This Weekend by Almost Half DirhamThe article allows the government to cap fuel prices within six months, subject to a one-time extension.In a press release issued earlier this month, Daoudi said that the opinion of the competition council was “not binding,” adding that the government will “cap prices regardless of the council’s position.”Daoudi is seeking to conclude a permanent agreement with companies as part of the negotiations conducted by the Moroccan Petroleum Group (GPM). The aim is to set a maximum profit that different companies can make, regardless of whether global market prices rise or fall. read more

UN chief confers with European security body on tensions in Kyrgyzstan

13 June 2010Secretary-General Ban Ki-moon conferred with the chair of the Organization for Security and Cooperation in Europe (OSCE) on the mounting tensions in Kyrgyzstan, as the United Nations assesses humanitarian aid needs arising from the violence that has reportedly claimed nearly 100 lives. According to media reports, violence is spreading in southern Kyrgyzstan on the third day of ethnic fighting between Kyrgyz and Uzbeks which has also led to the wounding of several hundred. During a phone call on Saturday with Foreign Minister Kanat Sauabayev of Kazakhstan, the Chairman-in-Office of the OSCE, Mr. Ban said he was alarmed by the scale of the clashes, the inter-ethnic nature of the violence, the mounting casualties and the large number of displaced people. The Secretary-General said the UN was urgently assessing humanitarian aid needs resulting from the clashes, the latest unrest to hit the Central Asian nation after the violent uprising in April that ousted former president Kurmanbek Bakiyev.Miroslav Jenča, the Special Representative of the Secretary-General and head of the Regional Centre for Preventive Diplomacy for Central Asia (UNRCCA), was in the southern city of Osh last Sunday and is continuing his efforts to ensure the peace and stability of Kyrgyzstan.

Brock prof part of international mission to save Caribbean history

Brock Education Professor Lissa Paul is part of a multinational rescue mission to preserve an important resource of Caribbean history and culture.Paul joined forces with a digital librarian in Florida and archivists in Barbados to successfully apply for a grant from the British Library Endangered Archives Program for a proposal to digitize copies of the Barbados Mercury Gazette, a bi-weekly newspaper published between 1783 and 1839.With microfilm copies of the Gazette quickly disintegrating and the only paper copies stored and sealed at the Barbados Archives Department, the material is essentially inaccessible to scholars.Based on her research experience with the Gazette, Paul provided the scholarly rationale to support the grant proposal submitted by colleagues Ingrid Thompson, chief archivist of the Barbados Archive Department, and archivist Amalia Levi.The project wouldn’t have come about, says Paul, if not for Laurie Taylor, of the Digital Library of the Caribbean (dLOC) based at the University of Florida. She was the “super connector,” bringing together the right combination of people to make the application possible.The grant of more than $45,000 will help ensure that historians and scholars from around the world will be able to access the Gazette.Paul became acquainted with the Gazette several years ago while visiting Barbados for her research into British author and teacher Eliza Fenwick (1766-1840). Prior to running a school for girls in what is now Niagara-on-the-Lake in the 1830s, Fenwick had run a similar school in Bridgetown, Barbados.“In my own research, I could correlate information I was finding in ads about Eliza’s school with information I was finding in her manuscript letters and in other records of life on the island in the early 19th century,” Paul says. “I came to recognize that the paper was an extraordinary source of information about the complex dynamics of day-to-day life on the island. In particular, it had value to scholars interested in the history of resistance by the enslaved people of the island in the years prior to the abolition of slavery in 1833.”Paul’s concern about the future of accessing the paper began in 2012 when her initial requests for copies of the microfilm were rejected. As the British Library later explained, the diazo microfilm medium on which they’d been produced had never been intended for preservation purposes, and were uncopiable. Over the years, as Paul used the microfilm copies she could access, she was alarmed at the rate at which they were deteriorating. Some pages had faded to gray mist, and the films themselves could barely be coaxed through readers.In the fall of 2016, Paul made a concerted effort to raise awareness about the Gazette during a presentation in Barbados at Cave Hill, University of West Indies. That was the turning point in finding stakeholders who shared her concern.The initial application was submitted to the British Library in November, 2016 and approved in principle this summer. Final approval to proceed came through three weeks ago.“I’m still struck by the unlikeliness of our connections and the odds against our being able to collaborate on the application,” she says. “One of my roles in the later phases of the project, once the digitization is complete, will be to create awareness about the Gazette’s historical and scholarly value.”Paul says she is considering organizing a conference in the fall of 2018 or winter of 2019 that could potentially focus on foregrounding resistance strategies by both Caribbean and North American enslaved people in the early 19th century. read more

Focus should be placed on safeguarding local intellectual property rights Opposition

…says copyright legislation will impact small businessesA local push cart music vendor (hiveminer image)Based on the announcement of Government’s intention to table copyright legislation, Opposition Leader Dr Bharrat Jagdeo has expressed worry over the impact this could have on the local economy as many businesses could possibly close as a result of the incoming change.As such, the Opposition Leader recommends that the current Administration should focus on protecting the intellectual property of local producers.Speaking at his weekly press conference on Thursday, Jagdeo explained that Guyanese artiste and writers have been lobbying for several years to protect their products from being copied and mass produced without their permission as many local producers cannot get royalties and earnings from their intellectual property.Opposition Leader Dr Bharrat JagdeoJust last week, Government signaled that it will table legislation to bring copyright laws on the books but those opposed to the change say it could put undue burdens on local producers of DVDs and CDs and that it will drastically impact on the foreign movies and television programmes currently broadcasted on television.Jagdeo weighed in on the issue at his press conference on Thursday, highlighting the economic impact this overhaul could have on local businesses.“I hope that people will understand…It will be a revolution in the Guyana, I’m not going to say much more because this Government when it passes that next year, every video store in this country will have to close that sells these bootlegs. And every store that sells music now… the way they currently do it will have to shut those down too as well as the guys who are doing the push cart they can be charged too” Jagdeo revealed.While acknowledging that some may be in disagreement with his position, he clarified that Government should place more emphasis on protecting local intellectual property rights rather than focusing on safeguarding international content.“In many parts People don’t protect our people, our material, so we protect the copyrighted material for our local artiste etc and we have those enforced and removed from the shelves etc and then wait until the appropriate time because we are a poor developing country, wait until such time in the future that people can afford to pay” the Opposition Leader suggested.There are currently small fines for copyright infringements under old laws. In fact, Guyana’s Trademark Act and Patents and Design Act were tabled in 1973, whilst the Copyright Act is dated 1956, decades before inter-connectivity was a basic part in the lives of many Guyanese in coastal and some hinterland areas. (Shemuel Fanfair) Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window)RelatedLGE 2018: Jagdeo points to increase in taxes as APNU/AFC mum on campaign trailNovember 7, 2018In “latest news”Parking meter project: Nothing short of scrapping will suffice- JagdeoFebruary 10, 2017In “latest news”Opposition Leader restates call for int’l probe into fake SoPs during 2015 electionsMarch 7, 2016In “latest news” read more

Wear Protection for Mining Equipment Processes

first_imgThe Liebherr GET solution is compatible with mining backhoes and face shovels from the R 9100 up to R 9400Metso, a market leader in grinding mill liners, is expanding its rubber mill lining production capacity globally by investing in new presses to meet the growing demand in the global mining market. After completing the investment in 2015, Metso’s global rubber mill linings production capacity at the existing wear part manufacturing plants will increase by 30%. The €10 million investment will be completed in two phases. The first set of presses is scheduled to be in operation by the end of 2013. It includes the installation of presses in Chile, Sweden, Canada, Mexico and Peru. Decisions for the second phase will be done based on the demand outlook in early 2013 and implemented in 2014-2015. Metso currently has wear part manufacturing units on six continents.“This investment is in line with our strategic plans to strengthen our offerings in services business and expand the mill linings availability to meet the growing demand”, says João Ney Colagrossi, President, Services business line, Metso’s Mining and Construction segment.“We are committed to on-time delivery of parts to our customers. Logistical agility is only assured if our operations are located close enough to the customer sites”, says Rodrigo Gouveia, SVP, Services business line.Metso Megaliner weighs up to 60% less than a metallic liner of similar sizeThe growing population of large grinding mills and the high utilisation rates of existing mills are driving demand for large, high-quality grinding wear parts. Using large sized liner assemblies reduces the number of pieces to be handled and shortens the duration of the maintenance shutdown.  “Metso has developed mill lining solutions, which combine rubber and a variety of steel elements to optimise the weight, wear life and ease of installation of liner systems. With our state-of-the-art technology, we are able to help our customers to maximise the productivity of their operations utilizing the best selection of materials for each application”, Gouveia adds.The new Metso MegalinerTM shell liner aims to keep downtime in large mills to a minimum, using an innovative design that offers speedy replacement. It also improves worker safety during maintenance, as the liners are bolted into position from the outside of the mill, so workers do not need to stand in the liners’ ‘drop-zone’.  Mill availability is improved through faster liner replacement. Megaliner uses larger than average liners, yet these can still be placed with the same 6- to 8-axis liner handlers used with many large AG mills.  Using larger liners means mills require fewer of them and Megaliner also has fewer attachment points compared with conventional liners, speeding up installation even further. Liners are easily and accurately positioned before bolting with the aid of highly visible, coloured guiding markers.The Megaliner is suitable for large AG mills with large trunnions and where modern liner handlers are available. Each Megaliner element integrates multiple lifter and shell plate rows, and covers an area up to 4 m2. The rubber / metal composite liner weighs between 30% and 60% less than metallic liners of a similar size.  Overall installing and replacing mill liners can be accomplished with the Megaliner system in a much safer and less stressful way.Weir Minerals Africa recently received three orders for Anglo American’s Goedehoop Colliery in Mpumalanga, totalling more than 90 t of dewatering screens of various sizes as well as spare parts for the mine’s stockholding. Weir Minerals Africa’s Chris Dorlas says the first order, placed by the colliery, calls for 10 Linatex® VD dewatering screens. All screens feature 3CR12 stainless steel deck frames to combat corrosion and each one has been test-run for eight hours to ensure that it works to the required performance levels. “These dewatering screens incorporate a 45° sloping back deck section, fitted with slotted apertures across the direction of flow,” Dorlas explains. “Incoming slurry is fed uniformly along the top of this back section, which acts as a vibrating drainage panel. The main deck of the screen slopes upwards at 5° and is fitted with smaller slotted apertures.Looking generally at the sector, Weir Minerals reports that the cost of installing and operating a new coal mine, for instance, “has increased nearly threefold in the last few years. The story is nearly the same around the globe and no one anticipates any relief in the near future.” The hard rock industry also faces such escalating costs. Many mines around the world are looking at their equipment and focusing on maximizing efficiency and productivity to get more with less.The Nordic steel distributor Tibnor, a part of SSAB, is an important player when more ore is to be mined in northern Sweden. More than 1,000 new ore wagons have been constructed by Kiruna Wagon, with Tibnor supplying the steel for the ore baskets. The 50th train set is currently under production. In total, 15 new train sets for Malmbanan (the iron ore railroad) are involved, with 68 wagons in each set. Kiruna Wagon is constructing the wagons, which have been ordered by LKAB. Each wagon has an ore basket capable of carrying a load of 100 t. The ore baskets are manufactured of laser-cut and laser hybrid welded steel from Tibnor. The transaction represents part of a new customer concept within the SSAB group, in which deliveries of advanced high strength steels are combined with logistics and production services.The LockLift (shown here) and Safe-T Lift lifting devices are used in conjunction with CME’s Linersafe range of manganese crusher wear liners. This partnership should allow Boral to realise cost savings through a choice of different liner grades and manganese percentages, chosen from the wear liner range“The transaction is an affirmation that complete solutions, in which SSAB’s steel knowhow is combined with Tibnor’s services, create customer value,” says Mikael Jansson, Director at Tibnor’s Marknad Sverige. “With this new customer concept, we are exploiting our shared expertise to an even higher degree than previously.”The steel selected for the ore baskets is hot rolled DX 355 MCE and DX 650 MCE from SSAB.  Tibnor is co-ordinating the flow of material and laser cutting the steel at its subsidiary, EM Eriksson, with production in Borlänge. EM Eriksson laser cuts ends and sides, and bends top beams and cross bars for the ore baskets.  Thereafter, the steel proceeds to Duroc in Luleå, which carries out laser hybrid welding, before Kiruna Wagon completes the production.Ted Anderses, CEO of E.M. Eriksson explains:  “We were acquired by Tibnor in the summer and, by being able to contribute our expertise to this solution, it feels as if we are already an integral part of the SSAB group.”  LKAB’s iron ore wagon design in high strength steel was nominated to the Swedish Steel Prize in 2008.News from the other side of the world has Crushing and Mining Equipment (CME) to be the primary supplier of crusher wear parts to Boral Construction Materials’ Australian operations in all states except Victoria and Tasmania, where it will be the secondary supplier. This agreement provides for the supply of CME’s manganese wear products for cone, jaw, gyratory, VSI and HSI crushers while CME will continue to supply a range of crusher and screen parts as well as providing on-site and off-site servicing and labour to more than 40 Boral sites Australiawide.One of Boral’s central tender requirements was for the safe lifting of crusher liners. This was a contributing factor in CME’s selection as it will provide its patent-pending LockLift and Safe-T Lift lifting systems. These were developed in response to safety issues associated with lifting crusher liners and providing quick, reliable and zero-harm servicing capabilities.  CME’s proprietary wear modelling software will provide Boral with application specific performance at the lowest total operating cost by matching the optimum profile with the most appropriate grade of manganese steel.Protecting pipes and moreWeir Minerals Linatex introduced its new Linatex® Wear Indicator System at the 2012 MINExpo International in September. This, it says, “is a revolutionary early warning system for hoses that handle highly abrasive materials in mining operations. The Linatex Wear Indicator System has a 24-hour monitoring system that transmits and receives information, relaying the message to operators onsite.Geoff Moore, Divisional Sales and Marketing Director, Weir Minerals explains: “With the Linatex Wear Indicator System, mine operators can create a safer environment for employees and the surroundings by closely monitoring the wear on equipment and proactively planning equipment maintenance”Within a short period of time highly abrasive material puts extreme wear and tear on the hose, causing operation shutdowns and extended periods of maintenance downtime, along with physical inspection. The Linatex Wear Indicator System provides a solution to many of the traditional issues surrounding the maintenance of hoses in highly abrasive environments.Linatex Wear IndicatorA standard wear indicator system only checks for a break in the wire (continuity) to detect a go/nogo hose failure point, but the Linatex system is constantly searching for wear and tear throughout the hose. When an area is detected it transmits messages, allowing maintenance to become a proactive process rather than a reactive one.The system senses a change in resistance (measured in ohms). This precision measurement provides more accurate results.  Water, being a conductive media, could cause a false positive, making the hose appear to have more wear life than it actually had. The Linatex system can therefore be used with conductive or non-conductive slurries with confidence, states Linatex. With the 24-hour monitoring system there isn’t a need for operation shutdowns for physical inspection or costly emergency maintenance downtime.Paula Russell, Hose Product Manager at Weir Minerals – Linatex told IM: “An oil sands hose may weight over 6 t and convey material at over 500 psi – wearing through a hose like this to the point it bursts or leaks material can be at a minimum a maintenance nightmare and at worst an environmental disaster. Maintenance and safety mangers alike need a proactive sensor to alert them to when a hose is nearing its end of life and action needs to be taken.”A Hose Transmitter can be paired with each hose and report the hose condition daily. This data can be transmitted over distances of more than two miles depending upon site conditions. Data collected by the receiver is transferred to a PC via a communication link to the Linatex Wear Indicator System software program. This displays identity, location and wear status of hoses, including alarms without requiring maintenance teams to visually identify potential wear in a hose.CertainTeed and Innoveyor teamed up to demonstrate the benefits of high-impact, restrained-joint PVC pipe at MINExpo 2012. CertainTeed’s Certa-LokTM YelomineTM restrained-joint pressure piping system was displayed as well as Innoveyor’s YeloRoll® conveyor rollers, which are manufactured with Yelomine pipe.  John Coogan, Channel Marketing and Communications Manager for CertainTeed’s Pipe & Foundations Group explained that “for the past 40 years, Yelomine has been a reliable choice for mining operations around the world. Its specially formulated PVC compound is perfectly suited for the rigours of today’s mining operations.”Engineered for strength and endurance, Yelomine pipe contains impact modifiers for higher impact strength over extended periods, with average impact values up to five times greater than conventional PVC, it reports. It is extremely resistant to harsh environments, acids and most chemicals, and won’t rust or corrode.  Yelomine also includes ultraviolet inhibitors that allow the pipe to be used in exposed aboveground locations.Innoveyor’s YeloRoll rollers are designed for a “drop in” retrofit into customers’ existing conveyor idler frames. The company says the “YeloRoll conveyor idler roll is 60% lighter, helping to prevent injuries and is 50% quieter than metal can rolls. In addition, it won’t rust, corrode or damage conveyor belts and can be recycled or rebuilt for future use.Richter Chemie-Technik manufactures fluoropolymer PFA/PTFE lined corrosion resistant process pumps and valves and is looking to increase its penetration in the mining sector. Its focus is on highly corrosive applications where the application cannot sustain conventional metals (cast iron, carbon steel, stainless steel 304 + 316) or standard plastics (PVC, PP) “because these would not resist the corrosion,” Manfred Kluge, Manager Marketing & Business Development explains.  “Instead customers would either have to select PFA/PTFE lined equipment (like ours) or go with more expensive equipment made of special metals like Duplex, Hastelloy, titanium etc.  “Besides high and highest corrosion our products can also resist temperatures to 150-200°C and pressures to 16-20 bar.”Victaulic has introduced the AGS Vic-Ring System that eases the installation of and provides a strong connection for large-diameter pressure piping systems up to 1,525 mm, while extending the service life of abrasive services piping.  The system consists of Style W07 rigid AGS (Advanced Groove System) couplings, style W77 flexible AGS couplings and specially designed rings containing a patented AGS groove profile.  Rings are butt welded to the pipe-ends, and the coupling is assembled on two rings-one on each pipe end-to complete the joint. Style W07 couplings create a completely rigid joint, while Style W77 couplings allow limited linear and angular pipe movement at the pipe joint that can be used to accommodate thermal expansion and contraction, vibration, seismic movement and other applications requiring flexibility.It simplifies the installation of large-diameter piping systems. The unique wedge-shaped key profile of the AGS groove results in easier initial assembly alignment. In addition, couplings 660 to 1,525 mm feature lifting lugs integrated into the housings to help ease handling during installation.The AGS Vic-Ring System can extend the life of abrasive service piping systems by maintaining the full pipe-wall thickness and creating a smooth flow path. The centre lip of the coupling’s FlushSeal gasket creates a barrier between the pipe ends, ensuring a smooth flow path and allowing the couplings to be used on lined pipe. In addition, the couplings allow the pipe to be easily rotated, further extending the life of the system. The AGS Vic-Ring System is ideal for large-diameter slurry and tailings lines, as well as other abrasive services.Feeders, screens and crushersAbreco Octagon Buttons (code AI-206) that were installed on the lower shell of a 60 x 89 gyratory crusher in March 2006 for Iron Ore Co of Canada. Over three years, maintenance on the lower shell was virtually eliminated with only minor repairs on regular service days. Removal of the spider and mantle is not required for initial installation or button replacement, saving valuable downtimeKeith Holbrook, President, explained to IM that Canadian Wear Technologies is “a manufacturer and manufacturer’s representative of premium wear resistant materials, covering basic to advanced wear protection. Our manufactured material is trade named Abreco and consists of a cast chrome white iron wear layer that is metallurgically bonded to a mild steel backer plate.“Chrome white iron is renowned for its wear resistant properties, however on its own, it has two major deficiencies; 1) at 700+ BHN (63 Rc) it may fail under heavy impact and 2) this type of white iron in not readily weldable. The Abreco process of metallurgically bonding the white iron wear layer to a mild steel backing overcomes these two deficiencies providing impact resistance and weldability. Engineers can now specify chrome white iron in applications they would never have considered before, such as primary crushing circuits. In addition to the standard inventory products such as Chocky Bars, Buttons and Skid Bars for the GET side we specialise in custom design products for fixed plant.“The Abreco wear system has been field proven for five years in hard rock mining to significantly reduce operating cost and increase equipment uptime. We have successfully extended the life of transfer points in conveying systems from six weeks to 12 months and apron feeders from 6 months to 24 months and liner changes in the surge pit area have improved from 15 liners every two weeks to 12 liners every 13 weeks.In order to increase the reliability of the primary crusher discharge apron feeders at an Iron Ore Company of Canada facility, a new type of liner was designed and tested. The aims were:■ Safety: in that the old style Chrome Carbide Overlay (CCO) liners were difficult to handle during installation with many finger pinch points■ Weight: The new liners had to be no heavier than the old style liner■ Increased service life: a target of twice the service life of 12 mm + 12 mm CCO liners was set.The Abreco Honey Comb liners supplied were thicker than the old style CCO liners yet weighed the same, and were much easier to handle. The unique Honey Comb design allows the ore to be trapped in the pockets creating material on material wear.  After two years of experience with the Honey Comb Liners they were shown to last seven times longer than CCO – an estimated 61 Mt of throughput before replacement. Furthermore, new style Abreco bottom skirt liners showed the same results.Commenting on the “great improvement in wear life in our crusher discharge apron feeders” after some years, Charlie O’Keefe – Supervisor Crusher Maintenance noted: “The cost is higher but it is well worth it when you have fewer interventions for maintenance and improved up time for production.”Abreco is also proving itself in abrasive slurry pipe applications. Holbrook explained that “AbrecoPipe is the world’s first and only “centrifugally cast, bimetallic white iron, seamless and UT testable wear pipe” that can be formed into long radius bends. It outlasts chrome carbide weld overlay pipe in highly abrasive oil sands tailings lines by a factor of seven.”Jeffrey Rader, part of the TerraSource Global group, says its NF electromechanical vibrating feeders “are precision-tuned near their own natural frequencies. They are ‘in tune’ with the materials they carry. These sub resonant tuning characteristics ensure efficient material transference, promote quieter operation, and reduce energy and maintenance costs.”The computer-designed deck with rugged drive structure handles large lumpy materials with greater reliability. Importantly for wear, the positive drive cog belt eliminates high-tension friction and reduces wear commonly associated with V-belt drives.  Maintenance costs are reduced because frequent belt adjustments or replacements are not required. Constant belt tension prevents slippage, extending bearing life.W.S. Tyler featured its Pro-Deck System at MINExpo 2012 – a new approach to maximising a screening system. The Pro-Deck approach implements an analysis and modification strategy in processing operations to maximise screen productivity and minimise wear by selecting the appropriate type of screen media according to the three phases of screening. This consultative approach results in a fully optimised screening process for greater efficiency and productivity, as well as less unscheduled maintenance and extended screen life.Wear-resistant materialsRuukki, one of the world’s leading producers of high-strength and wear-resistant steel grades, was described in detail in the recent Nordic technology focus (IM, October, 2012, pp57-58).  Ruukki Raex wear-resistant steel has been engineered to withstand even the most demanding conditions, making it a safe, costeffective choice for the needs of mining. For end users, the excellent wear-resistance properties of Raex mean less wear in structural components, which in turn results in the longer service life of components and machinery. Raex allows innovative engineering and lightweight structures with enhanced energy efficiency.EN Raex improving lifeRaex wear-resistant steel is available in four hardness classes: Raex 300, Raex 400, Raex 450 and Raex 500.  The company says that “use of Raex can usually reduce the thickness of a structure by 30 to 50% compared to ordinary structural steel – without compromising on abrasion resistance. Hardness class 400 is the most commonly used at the global level, but demand is also increasing for 450. Both steel grades have good formability and weldability, in addition to excellent wear-resistance properties.”Raex 400 steel is an excellent material for long-term, heavy-duty use and parts which are susceptible to strong surface pressure, such as loading areas that have to withstand the impact of rocks. The hardness of Raex 400 is 2.5 times that of ordinary structural steel. Raex 500 is ideal for abrasive environments with extremely high surface pressure, such as excavator buckets. The hardness of Raex 500 is three times that of ordinary structural steel.By using advanced direct quenching technology developed in-house, Ruukki can quench plates and strips immediately after the hot-rolling phase. This significantly reduces both production time and energy use and enables the mill to deliver plates to customers in record time. Direct quenching offers several benefits:■ Excellent surface quality, because the surface is freshly rolled without the effects of secondary heat treatment■ Best in class thickness and weight tolerances, Ruukki says. This is important especially for thin gauges where relative weight control is critical■ Flexible production capacity ensures fast mill deliveries.Cabot Corp has just launched TransfinityTM XD7050 reinforced elastomer composite, which extends the wear life of rubber components used in mineral processing plants. This new class of material is specifically tailored for use in mining applications. Mines can benefit from the high durability of this new material that increases the service life of parts, significantly reduces maintenance downtime and cost, and increases output from existing assets.“Rubber mining components made with Transfinity XD7050 material demonstrate superior mechanical properties and extended wear life when compared to parts made with conventional rubber compounds,” the company reports. “The material delivers superior resistance to abrasion, wet erosion, cutting, chipping and tearing, allowing mineral processing equipment to run up to 100% longer between maintenance shutdowns.” Transfinity XD7050 material can provide wear protection in various applications such as grinding mills, slurry pumps, cyclones, trommels, chute liners, dry screens and conveyor belts. This improved wear life directly impacts plant performance by significantly reducing maintenance downtime and costs on critical equipment which ultimately helps increase plant output and minerals recovery. Transfinity materials have been successfully used in field trials that resulted in 20 to 100% improvements in durability.Russell Coverley, Cabot Elastomer Composites Business Manager says: “Components made with Transfinity XD7050 material have been proven to last longer and extend service intervals for mineral processing equipment.  These performance and productivity improvements can translate directly into higher profitability and returns on assets for mine operators.”Cabot’s patented technology uses liquid phase mixing rather than conventional dry phase mixing in order to incorporate reinforcing agents such as carbon black into elastomers.  This technology enables Transfinity products to have a superior level of dispersion of the carbon black which creates composites that are stronger than those produced by conventional mixing. Transfinity products are a Cabot brand of composites made from elastomer latex (a liquid form of rubber) and reinforcing particles, such as carbon black. Through the subsequent addition of curing agents, Transfinity elastomer composites can be moulded or extruded and vulcanised to create shaped elastic parts.Earlier this year NanoSteel® Co, a leader in nano-structured steel materials design, was awarded its fifth R&D 100 Award, by R&D  Magazine, for the development of a new class of nano-structured powder metal alloys designed for making large scale industrial components.  NanoSteel’s patented designs are the company’s first commercially available materials based on its recent breakthroughs in highstrength steels with exceptional combinations of strength and ductility.This new class of steels features nano-scale microstructures which can be used in hot isostatic pressing, known as “HIPing,” to form components. These nano-scale structures result in a powerful combination of high tensile strength and elongation properties with high corrosion and/or wear resistance.“Previous strategies to alter the mechanical properties of steel to form near net shape components with nano scale microstructures have been severely limited by size and total thickness,” said Daniel Branagan, CTO and founder of NanoSteel. “The proprietary chemistries and new mechanisms at the core of our recent breakthroughs have allowed us to successfully engineer steel so that components weighing up to several thousand pounds can be formed with nano-scale microstructures and produced in volume on a large industrial scale.”Parts formed with NanoSteel’s powder metallurgy can increase dependability in highly stressed and operationally critical applications.  Over its ten-year history, NanoSteel has created progressive generations of iron-based alloys from surface coatings to monolithic steel.  For the mining industry, it has successfully introduced commercial applications of metallic coatings to prolong service life in the most extreme environments.Carryback on dozer blade before and after ARCOPLATEAlloy Steel International has many years of experience in providing services to leading mining companies in 25 countries. According to company founder and CEO, Gene Kostecki, “ARCOPLATE has won the confidence of the largest mining operators with proven savings and a wear life up to six times greater than traditional wear products.  Our company is unique in that we partner with our customers, offering the best wear solutions that deliver savings and amazing returns on investment.  ARCOPLATE has been widely adopted by major companies involved in mining and mineral processing, as well as by leading original equipment manufacturers.”The product is used in the toughest abrasive environments to protect crusher and bin liners, chutes and a host of other fixed plant. Its slicksmooth surface also greatly reduces material hang-up and carry-back in mobile plant such as truck trays and excavator buckets. Kostecki:  “ARCOPLATE saves on three fronts; reduced wear costs, reduced labour costs and most importantly reduced downtime.”Abresist Kalenborn is celebrating its 35th year in business this year, manufacturing and installing a wide range of mineral and ceramic based abrasion-resistant protective linings.  Founded in May 1977 as Abresist Corp, its company name changed to Abresist Kalenborn Corp in January 2011. It is part of Kalenborn International, a parent company to 12 subsidiaries with facilities in Asia, Europe, North America and South America.ThyssenKrupp Steel Europe offers XAR® (eXtra Abrasion Resistant) and says “thanks to their high level of hardness achieved by special chemical composition and quenching and tempering heat treatments during steel production, wear is minimised and lifetime extended”. The first XAR plates were produced more than 40 years ago in Duisburg. Since then, these steels have been continuously improved so that now various grades are available with plate thicknesses from 3 to 100 mm, for a range of applications in mining, such as for earthmoving equipment.The standard wear-resistant steel grade is XAR 400, which increases product service life to five-fold the lifetime of conventional structural steels under equivalent operating conditions, while simultaneously combining high wear resistance with good cold formability and weldability, the company claims. A heatresistant XAR 400 W is also available for applications requiring high hardness and wear resistance at temperatures up to 400 °C. XAR 450 is used where requirements call for higher wear resistance combined with virtually the same processing characteristics as the standard XAR 400 grade. For particularly abrasive wear, the steel grades XAR 500 and XAR 600 are available, which combine formability and weldability with extreme abrasive resistance. For applications with increased toughness requirements on the wear plate, XAR HT is the choice with its combination of wear resistance and high notch impact strength.The company also notes that an analysis published by the Institute of Tribology at Mannheim University of Applied Sciences “has proven that within the range of low-alloyed, wear-resistant special structural steels with good processing characteristics, XAR steels with hardness values from 300 to 600 HB represent an excellent concept with regard to steel composition, manufacturing process and microstructure. Extensive tests on the wear behaviour of the materials showed that optimum abrasion resistance is achieved thanks to their high hardness and in particular to the selective alloying with chromium and niobium.  The toughness and cold-formability as well as resistance to impact wear are increased by niobium micro-alloying. Chromium alloying improves wear resistance in aggressively corrosive media. The lean analysis concepts and the low carbon equivalent of the XAR steels make cutting and welding easier and provide better cold forming characteristics with tight bending radii.”  Additionally, a comprehensive technical customer service provides support in all material processing, design and wear questions.ThyssenKrupp Steel Europe says it “wants to be more than a reliable material supplier. The development and expansion of the worldwide distribution network is aimed not just at guaranteeing the availability and just-in-time delivery of XAR steels to consumers. The close cooperation of the new team Special Products & Services together with first-class steel service centres also enable the supply of prefabricated components.”Astralloy says its EB 450 “is a liquid quenched and tempered, through-hardened, high impact, excellent abrasion resistant alloy steel. It features a balanced boron modified nickel-chrome-moly chemistry for optimum hardness to toughness ratio.” It offers longer wear life because the through-hardness is more uniform than conventional carbon/manganese steels. Resistance to atmospheric corrosion further reduces surface pitting. It is field proven in major abrasive bulk handling installations.K-ALOX ceramic lined slag granulator break box repaired by Kingfisher Industrial. The company says “it cost less than the alternative of replacing the old break boxes with new units and it will outperform the OEM’S design by a factor of 6 to 1”AstraWear 400F is a water tempered martensitic steel, with typical hardness of 400 BHN (42.5 HRC), which “offers real response to wear from abrasion,” Astralloy says. “Its resistance, high hardness, and high yield strength, make AstraWear 400F suitable for use in applications that require resistance to wear from scraping or moderate impact. Its resistance to wear makes it up to three times more durable than A572-50 (S355) grade.  AstraWear 400F welds easily and has excellent forming properties, which combine to facilitate processing.”Kingfisher Industrial has calculated that the cost of repairing plant and equipment such as transfer chutes, hoppers and silos, grinding mills & classifiers, screens and underpans, tanks, cyclones and separators, fan casings, feeders and conveyors averages around onethird that of buying new. “Repair of worn equipment, or perforated pipework is a really viable option at any time, but more so during periods of belt tightening,” said John Connolly, MD of Kingfisher Industrial. “Using a combination of ceramic, metallic and polymer lining systems, we have had overwhelming success in protecting equipment and extending the service life of process plant and equipment that, without intervention, would otherwise have been designated as scrap.“Our experience is that every installation requiring repair or refurbishment using wear protection has its own specific requirements in terms of lining material. There is no ‘one- sizefits- all solution’, due to the levels of abrasion of different conveyed materials. This contrasts with the procedures in many companies today, where the method of repair with wear protection is almost exclusively based upon applying hard metal deposits using traditional welding methods.“Although this can work in some instances as a means of extending plant life, it is not cost effective because it does not eradicate the continual problems experienced in many applications.”By applying the correct lining material, users can actually get more life from their plants than they thought possible. This is also means long term savings on maintenance costs and downtime. In addition, the improved efficiency of the lining material generally results in improved productivity. The latter benefit results from the low friction nature of the lining material, which reduces energy use and allows a greater volume of material to be handled.Wear protection also lends itself to the repair process, as it offers the flexibility to be implemented at any time during equipment life.  Most equipment is designed to allow access for cleaning, repair or replacement. As long as the substrate of the original equipment is not compromised through excessive wear or corrosion then it can continually be repaired in situ. Even if the substrate is compromised, Kingfisher says it can be brought back to a suitable working condition for reuse by replating, incorporating suitable surface preparation and protection.Ground engagingMTG has started a test period at its new plant in Monzon, Spain. The plant should be fully operative on the first quarter of 2013. It has been built specifically to expand the company’s mining product range and towards new markets, especially targeting emerging countries. The new plant is equipped with the most innovative technologies in smelter manufacturing and will increase the annual production of wear parts: teeth, adapters and shrouds for mining machines. Initial annual production is 10,000 t with the possibility of increasing significantly its capacity in the future.During MINExpo, MTG presented its first solution for electric cable shovels. The adapter, known as “whisler” is made with MTG Steels, which, it says, have been proven to be significantly more resistant than the competition. It can be combined with MTG’s new tooth TMA500WH1, which has been specially designed for use on electric cable shovels. The whisler is currently under test under the hardest, real conditions to ensure the maximum quality is achieved under any application.MTG has four new sizes for its hammerless StarMet system, featuring the bilateral MTGTwist fixing. It gives excellent penetration and more wear material; self-sharpening designs; easy assembling/disassembling; maximum strength and resistance and long adapter service lifeAdditionally, MTG launched four new sizes for its acclaimed hammerless StarMet system. With the new available sizes 15, 20, 30 and 40, especially designed for construction, MTG fully completes its product range offer for construction, heavy construction and mining.The new StarMet sizes are available on the most popular MTG designs. The new product’s main innovation is, the company says on “the lightest and the one with the shortest tooth nose available on the market. They incorporate the new Bilateral MTGTwist fixing system.Esco debuted its Nemisys lip system at MINExpo. The system features a cast or plate lip with shrouds and a three piece tooth system for large mining buckets. Nemisys is now available for hydraulic mining excavators in the 300 to 800 t classes. The system will also be made available for cable shovels and draglines.Esco engineered the Nemisys system from the ground up. The lip, shrouds and teeth were developed simultaneously under a new engineering process designed to maximise a machine’s productivity. “The Nemisys system was designed to give customers a safer and highly productive solution to their mining needs,” said Jon Owens, Senior Vice President and President of the Engineered Products Group. Testing of the new system indicates that compared to legacy systems, the lip design and ground engaging teeth require on average 10% less force to penetrate; teeth have up to 19% more usable wear metal; and the system on average weighs 7% less.These improvements provide increased productivity and reliability while reducing maintenance costs. Integral hammerless locking devices on points, adapters and shrouds and improved ergonomics also make the system safer for customers.Esco Nemysis systemJoy Global and Esco recently entered into a strategic business alliance. The first phase of which is the development of new lip systems with Esco technology for P&H® shovel dippers.  Joy Global Surface Mining will offer Esco’s proprietary lips and GET systems as standard on new P&H shovel dippers and loader buckets unless a customer specifically requests an alternative GET system. Esco will service the aftermarket on all lips through its distribution network.  Engineers from both companies will be collaborating on enhanced designs to improve reliability and productivity, while at the same time reducing lip and GET maintenance needs.Liebherr has developed a complete mining Ground Engaging Tools (GET) solution to complement its mining shovel bucket design.  This synergy enables easy material penetration while extending the life of the bucket. The so called “Z Tooth System” is available in three profiles to cover an extensive range of application types, from well blasted material to very hard ground.  The long-drawn pointed shape of the CLprofile provides a sharp cutting edge for superior penetration in rock and blasted material up to medium compacted ground.  With its wide, thick tooth sole the CR-profile delivers long service life in abrasive soils and blasted rock applications, and perfectly fits for a bottom dump bucket configuration.  The pointed shape of the P-profile offers optimal penetration for very hard and compacted ground applications.  Thanks to the self-sharpening teeth design, machine operators should find an optimal combination of bucket penetration and high fill factor over the life of the teeth.To reduce parts inventory Liebherr has designed a single wing shroud and corner wear caps for each model, interchangeable from left hand side, right hand side and top to bottom. To increase machine uptime and reduce tooling to one unique extraction tool, the teeth, shrouds and wing shrouds are equipped with one single locking system. In addition, the wear cap does not require any locking system as it is slipped on the adaptor and locked by the tooth.  With its unique hammerless locking system, the replacement of the teeth and the wing shrouds is simple: the securing pin, the tooth, and the adapter are quickly locked by a 90° tool manoeuvre.Black Cat Blades produces a complete range of quality wear parts for all OEM brands of earthmoving equipment – loaders, excavators, dozers and graders. Blades and end bits are fabricated using high alloy boron steels and heat treated to exacting specifications to meet the demanding needs of large earthmoving applications. High carbon alloy steel is used to manufacture many grader blades. Black Cat says “HighSpec alloy steels and strict heat treatment tolerances are used to ensure all cast wear parts are of the highest quality possible.”Bradken says it is the global leader in crawler shoe manufacture for excavators greater than 200 t. A recent success story was in gold mine in Tanzania, where harsh conditions can significantly increase the operating cost of the RH340 face shovels in operation there. The mine decided to install a set of Bradken Opti-Trak® crawler shoes after the original OEM shoes fitted to the machine were replaced after 16,000 machine hours.Bradken says “the Opti-Trak design offers some unique advantages over the OEM crawler shoe design. The substitution of the circlip retaining system with a nut and bolt has eliminated the downtime associated with circlip loss. The performance of the Opti-Trak shoes to date has been very impressive.” After 8,000 machine hours the shoes were showing no abnormal wear on the pins, drive lugs, bores or roller path. “The through hardened material provides consistent wear rates, whilst the improved roller path support provides greater structural integrity.”Boundary Equipment has an extensive line of replacement parts for Terex O&K RH120E, RH170, RH200 & RH340 mining shovels. It has been producing high quality undercarriage parts for the worldwide mining market for more than 30 years. Boundary can supply track shoes, Boundary PosikeepersTM, drive tumblers and front idlers to replace O&K undercarriage parts and says “if we don’t have the part you’re looking for, we can engineer it.”All replacement products for O&K parts are made to Boundary original specifications and result in genuine quality parts. Boundary Posikeepers are designed to last the life of the undercarriage and are a cost effective way to protect the pin bore and increase pin life. Track shoe pricing includes pins and Boundary Posikeepers.Founded in 1978 initially as a mobile welding repair and refurbishment business Miller cut its teeth in the mining and quarrying industry.  Offering a 24/7 service, the small Miller team back in the late 1970s was kept very busy constantly repairing worn buckets, attachments, dump truck bodies and other associated on-site plant equipment and machinery.Finite Element Analysis (FEA) used by Miller provides predictive performance in respect of loads and stressRepeated failures in the same areas got the Miller brothers Keith and Gary thinking that “this has to be a design issue” and it was this initial thought process way back in those early years that led the way to Miller designing its own bucket range.  Recognising early on in the then fledgling Miller company that to build a good business with a strong brand it must be able to offer customers real value and to do this it had to offer products that made a difference to their working environments. In most cases back then much debate was held over the machine, engine and productivity outputs but very seldom was any time spent discussing the bucket design, ironic when one considers it is actually this part of the machine that is responsible for loading and therefore has a huge impact on the machine’s overall output. This intrigued Miller as it began to look at how to use its product knowledge to design and develop improved buckets that would not only minimise buckets failing in the specific areas that they were becoming notorious for but also to look at incorporating into these designs new ideas on how to reduce wear, in other words extending the life of the bucket and so delivering customers more machine up time.Over the years with now countless numbers of ‘custom’ built bucket designs working worldwide Miller still continues to look at extending bucket life through a variety of solutions which can vary dramatically from application to application.  “We pride ourselves still on offering our customers a service like no other” explains Gary Miller, Technical Director. “We want customers to come back to us again and again so we spend time finding out about how to tackle their wear issues and what causes them the most downtime. Once we understand this we can build a solution to satisfy their exact requirements and not a standard off-the-shelf design, which will do a job but maybe not return the productivity the customer is looking for.”As the industry continues to change on a global scale so too does the demand from customers for improved cycle times and less wear. All sorts of options must be explored when trying to find the right solution, from new lighter, longer life steel grades to the latest wear packs and tooth designs from the various wear part suppliers.“Whilst we will never stop buckets or machinery wearing out, we can certainly reduce impact on machine productivity. Of course quality and longevity come at a price but on large mining projects around the world so long as the return on investment shows an improvement then companies like Miller will continue to play an important role in developing new ideas that help keep mines across the globe running for longer,” says Keith Miller, Chairman, Miller International.GET undergroundKeech Wearpact bucket edge system for LHDsA group of five mining contractors in Chile’s copper and gold mines is reporting impressive results from trials of the Keech WearpactTM bucket edge system on a fleet of underground loaders. The trials are at varying stages, following the start of the first trial over a year ago.  Wearpact is a patented ground engaging tool designed for both underground and open pit mining.  Heavy duty edges and corners perform under all loading conditions, keeping wear consistent across the edge.“We made a business decision to enter the Chilean market because we saw a real opportunity to make a difference,” said Keech International Sales and Marketing Manager, Mark Adams. “We appointed a business development manager two years ago and regular visits to Chile by myself to oversee trials and their implementation has proven invaluable in getting to know some of the leading contractors and talking to them about our Wearpact system.”After 12 months of the first trial – “2,000 hours with the Wearpact system showing no problems whatsoever. We may be able to get as much as four times the life out of the bucket thanks to Wearpact,” he said.Prior to installing the Wearpact system, the loader buckets needed to be transported many kilometers to Santiago for repairs.  After 1,000 hours in the second longest running trial, that contractor ordered two more Wearpact systems for the other loaders in the fleet. “Keech Chile now has purchase orders from contractors for another 10 Wearpact systems, which will be fitted to other loaders in the fleet over the coming months,” Adams said.Back in Australia, a new mechanical bucket is dramatically reducing the time required to replace edge wear systems on underground LHDs. The Keech Mechanical Bucket (KMB) features a complete bolt-on section at the front of the bucket, differing from standard buckets on the market.The KMB is on trial at the Newcrest Cadia East gold mine in Orange, New South Wales, following a 12-month development phase. The mine is trialing a 12 m3 bucket with an Armourblade edge system on two underground mining loaders, “and the results so far have been outstanding. “The KMB bucket front with the Keech ArmourbladeTM edge system can be replaced within three hours on site. Operators simply unbolt the front section and replace it with a new one,” explained Adams.“Given that the edges on some buckets need to be cut off, which can take up to 35 hours, the KMB is likely to generate significant efficiencies for underground mine applications.”  The ease of removal of the front section also means the bucket can run a welded edge, making it ideal for use in cautious areas such as crusher zones, while still maintaining a quick change out during underground operations to minimise downtime.  The KMB is compatible with both Wearpact and Armourblade edge system. Wearpact is a hammerless GET system, available in full spade and semi spade configuration, while Armourblade is a welded edge system.The Newcrest Cadia East trial is also evaluating actual edge life, which to date has tested at approximately 1,000 hours. “We’re currently investigating how we can extend this to 1,200 hours plus, and are looking at redesigning the corners, which are usually the fastest wearing area, through the addition of tungsten carbide inserts,” explained Adams.The buckets have been developed by Keech in conjunction with Canadian company Carriere Industrial Supply and are available in a range of sizes from 7 up to 12 m3. They are manufactured from quenched and tempered steel, and Keech works with each customer individually to customise a wear protection system to suit the application at hand. The bucket is suitable for all LHDs. IMlast_img read more

WebGL flaws puts Chrome and Firefox users at serious risk

first_imgBoth Mozilla and Google have sung the praises of WebGL and its ability to bring rich 3D experiences to users via the Web. According to security researcher James Forshaw, that extra dimension comes with a rather serious trade-off: your security.Over on the Context Information Security blog, Forshaw details several flaws in WebGL which could allow an attacker to infiltrate a user’s system and wreak havoc via the GPU and graphics drivers. These issues are particularly worrisome since WebGL is effectively granted access to kernel mode features “in what is supposed to be the most protected part of the computer.”AdChoices广告In addition to being able to render a system unusable (WebGL is already known to have been exploited in denial-of-service attacks), the vulnerabilities allow something which is potentially much more harmful. As illustrated by Context’s proof of concept, it’s possible to steal content which is being rendered on a user’s display. That means sensitive information you’re browsing – from bank account details to password reset questions and answers – could be exposed to malicious prying eyes.The proof-of-concept should work in any browser with WebGL support, including Firefox 4+ and Google Chrome 9+. Internet Explorer and Opera users are safe for now, though WebGL support is planned for the final release of Opera 11.50. Microsoft, however, has made it clear that it preferred to support technologies like 3D CSS and HTML5 layers — and it appears as though IE users can enjoy a little added peace of mind as a result of that decision.Forshaw recommends IT administrators (and users) disable WebGL until its security shortcomings have been addressed. That won’t be a simple task, he warns, and his closing words are actually quite ominous: “Perhaps the best approach would be to design a specification for 3D graphics from the ground up with these issues in mind.”via The Inquirer and Context ISlast_img read more

Worlds largest stopmotion Postit video uses 350000 Postits

first_imgYesterday we showed you the world’s largest stop-motion animation video which was shot on a Nokia N8 camera. Today, we have another world’s largest stop-motion video, but this one uses Post-it notes to garner the World’s Largest Stop-Motion Post-it Animation award.The video was created as an advertising scheme for a new Melissa shoe store in Sao Paulo, Brazil. Apparently, the shoe brand Melissa is big enough in Brazil to warrant such an elaborate promotion built in honor of the opening of the company’s flagship store, Galeria Melissa. The project took 25 animators over five months of time. To create the animation, Melissa teamed up with 3M and used 350,000 Post-it notes.The Post-its weren’t just part of the video, though; the giant canvas was opened to the public to come by and add their messages of love on the notes. The video’s theme is “the power of love,” based on the recently released Power of Love shoe collection. Of the 350,000 Post-its used in the animation, more than 30,000 of them had random love notes written on them from people visiting the massive Post-it exhibit.The result is a mammoth of a brightly-colored mural that’s rather impressive to look at. The video shows a girl being carried by a balloon through the Post-its, an elephant rearing up on its hind legs, and a flower radiating from the center of the piece. The videos also show some of the lovey-dovey notes that people contributed to, as well as some of the people themselves.We’d prefer to see more of the stop-motion animation and less of the people writing love notes on the wall, but it’s still a pretty amazing video considering the scope of the whole project.Check out a little “Making Of” video below for a few more glances of the amazing stop-motion mural.via Social Timeslast_img read more

SpaceX Dragon Returns to Earth With a Crew of Mousetronauts

first_img Yesterday, Canadarm2 yanked the SpaceX Dragon from the International Space Station. It was carrying thousands of pounds of precious cargo… including a team of rodent astronauts.These weren’t five-foot cartoon mice obviously, but opportunities to use Captain EO imagery don’t present themselves all that often in the blogging world. The Dragon was returning the Rodent Research-9 team, which SpaceX delivered to the ISS about a month ago during its 12th resupply mission.NASA scientists are using the Rodent Research-9 project to take another look at how the lack of gravity affects the human body — specifically blood vessels, eyes, and joints. Dr. Kevin Ames, a senior project scientist in NASA’s space biology unit, said: “the changes we see during this rodent research experiment will allow us to better prepare our astronauts for long-term exposure to low-gravity environments.”The three modules used by Rodent Research-9 (image: NASA): habitat, transport, and animal access (left to right)One particular change they’ll be investigating is the vision loss that some astronauts experience after extended stays aboard the ISS. NASA has previously reported that about 1 in 5 astronauts are affected. The symptoms, NASA says, closely resemble those brought on by vitamin deficiency.In a related 2012 study, NASA analyzed blood and urine samples collected by crew members. Researchers were excited by the results — which were admittedly “very preliminary” — and believed they could “have significant implications for NASA and future astronauts.”The mice from Rodent Research-9 will provide NASA scientists with additional insight into what happens to live tissue. While their findings will clearly help astronauts, the general public stands to benefit, too. NASA notes that the impact on their joints, for example, “can help scientists understand how arthritis develops in people.” The study could also “help identify causes and treatments for eye disorders.”Image courtesy Orlando Parks News NASA Says 2 Asteroids Will Safely Fly By Earth This WeekendHubble Captures Saturn’s ‘Phonograph Record’ Ring System Stay on targetcenter_img Let us know what you like about Geek by taking our survey.last_img read more

Best and worst days of the week to buy gas

first_img May 2, 2018 Updated: 5:03 PM SAN DIEGO (KUSI) — According to a study conducted by GasBuddy, “Gasoline prices are at their highest levels since 2014 and will continue to rise through Memorial Day.”Many metro areas are already seeing prices well over $3 a gallon, many places in San Diego County are even seeing prices higher than $4 a gallon.The new study  by GasBuddy has found the best and worst days of the weeks to buy gas to maximize savings at the pump and avoid the lines during the busy summer travel season. “The case of the Mondays” is not a thing when it comes to pumping gas. The study states, “Monday offers the lowest average gas price in 21 states, making it the best day to fill-up. Friday has the most expensive average and is the worst day to buy gas in 19 states.“Though there is variation in daily gas prices across different states, the consensus is that the earlier motorists fill-up during the week, the better,” says Patrick DeHaan, head of petroleum analysis at GasBuddy. “Following Monday, Sunday is the cheapest day to fill-up. Conversely, Thursday follows Friday as the most expensive day to fill-up.”Furthermore, the study found that “gas stations across the country are least busy on Sundays, followed by Mondays. And Friday is the busiest day to fill-up your tank.
