Carbon fibre CSI screens at MinRes ’ Mt Marion lithium mine
From carbon fibre to new global capacity additions and significant orders , Paul Moore looks again at developments in screening technology
One of the latest developments in screening technology is the use of carbon fibre , which is being pioneered by iron ore miner & mining services group , Mineral Resources Ltd ( MinRes ) in Australia .
Its crushing business , CSI Mining Services , is well known in the industry for its modular NextGen crusher technology – an alternative to higher-cost fixed plants which also offers reduced environmental impact across crushing construction and operations . MinRes told IM : “ With capacity ranging from five to 50 million tonnes per annum , CSI ’ s modular crushing solution delivers significantly lower dust and noise emissions , consumes less energy and can be rapidly deployed in remote operations . This year we launched our latest NextGen 3 plant , which has been enhanced to include carbon fibre vibrating screens . The in-house developed innovation replaces traditional steel vibrating screens , bringing a host of cost and productivity benefits .”
CSI ’ s carbon fibre manufacturing facility is a world leader in the use of carbon fibre for mining equipment . The team developed a carbon fibre vibrating screen which takes the place of traditional steel vibrating screens and brings a host of cost and productivity benefits . The screen components are lightweight , corrosion resistant and have a significantly higher structural strength than steel . Service life is also three to five times longer than steel screens .
The first carbon fibre screen was completed in the first quarter of this year and successfully installed at Mt Marion , with a series of additional screens for the hard rock lithium mine which is now in production . Carbon fibre screens are applicable in both wet processing and dry screening environments and can be built in less than six weeks at CSI ’ s carbon fibre manufacturing facility south of Perth .
AKW ’ s AKA-Screen
Germany ’ s AKW Equipment + Process Design has 60 years of experience in providing technical solutions for wet mechanical treatment challenges . In order to represent the complete treatment processes , be it in lab or full scale , AKW Equipment + Process Design extended some time ago its scope of supply with the addition of the AKA-SCREEN , wet classification screens .
The company told IM : “ With the lab-scale AKA- SCREEN , the team has the unique opportunity that enables to conduct extensive testing and research on different materials and process parameters . This allows to optimise each single process , improve the efficiency and in the end reduce the costs . Being flexible in customising
With the full-scale AKA-SCREEN , AKW Equipment + Process Design offers a series that is using two unbalanced motors with up to 2G acceleration and tailoring to meet the specific customer requirements is one of the unique selling propositions that AKW Equipment + Process Design is always striving for .”
With the full-scale AKA-SCREEN , AKW Equipment + Process Design is offering a series that is using two unbalanced motors with up to 2G acceleration . This generates a compositevibration of linear motion of the whole screen frames and additionally mesh vibration . The vibrating parameters can be controlled through frequency conversion . The AKA-SCREEN consists of up to five individual screen decks , available in standard or long version . Screen mats are made of reinforced polyurethane . The screen frame is entirely coated with polyurethane , and integrates a spraying system as well as a repulper ( as an option ) for optimum screening efficiency .
The company adds : “ Be it for ores and minerals , commodity or specialty sands , the AKA- SCREEN series offers a fully automated and low energy system that is robust , performant and highest competitive .”
