MINING SCREENS
in Dülmen , Germany . The Roy Hill vibrating grizzly screen is designed to handle up to 4,300 t / h of iron ore and caters for a maximum particle size of 2,400 mm x 1,450 mm . The vibrating grizzly screen is a mechanical screening device and is utilised to separate large particles from a smaller fraction in order to allow each size fraction to be treated downstream in the process . In this application material from the ROM bin discharge apron feeder is fed to the vibrating grizzly . The vibrating grizzly screen undersize discharges material to a conveyor and the oversize is discharged directly into the primary jaw gyratory crusher . The company stated : “ This significant project reflects JOEST Australia ’ s proven capability and experience in delivering a reliable solution to the industry and now the Roy Hill mine site . This unit is the first JOEST Grizzly for the Roy Hill operation and adds to JOEST Australia ’ s growing list of worldwide installations . The robust construction and userfriendly maintenance features offers an effective solution for treating large tonnages with the benefit of cost-effective plant design and simplicity of operation .”
In late October 2020 , after one year of planning and designing and additional ten months of construction , the JOEST Australia team moved into a state of the art new facility in a logistics park on Coldwell Road , Welshpool , after having operated from Sheffield Road for
over 15 years . Especially in the mining industry , the rising demand for larger machines required a new facility after the old one exceeded its capacities . This new location enables faster and more efficient manufacturing of machines and also helps meet the clients ’ rising demands . The 10,000 m ² property includes offices as well as the new workshop . A special design drastically reduces the noise emitted to the administrative part of the new headquarters . The large and open office area has room for over 40 employees , so design engineering , sales and purchasing can work together seamlessly . In addition to the open floor plan for the offices , there are separate areas for members of the management team .
With over 4,000 m ², three equally large assembly bays provide plenty of room for production , assembly and a separate storage area . To ensure an optimal production flow , multiple cranes with lifting capacities ranging from 5 to 50 t run the length of the workshop . Alongside a new painting booth , the new workshop features a clean room , enabling gearbox and exciter service and repairs . The new plant represents the biggest single investment JOEST Group has ever made .
CDE continues to expand Infinity range
Wet processing industry expert CDE first launched its patented Infinity Screen™ range to
market after securing a global patent for the construction of the screen sidewalls . The company told IM that the range has been a significant success , with customers valuing the durability and prolonged operational life of the products . “ This results from their unique construction , with no welds in the sidewalls , making them fundamentally different from other screens available on the market .” It now has 15 Infinity-branded screens for dewatering and product sizing classification in the full range . “ It ’ s a range that boasts a lot of unique features , including a fully-bolted construction with patented trilogy side wall technology which reduces the risk of cyclic fatigue failure ,” explains Daniel Webber , Australasia Regional Manager at CDE . “ No cracks mean no welding or patching and , crucially , no downtime to ensure maximum performance and fast return on investment .” Commenting on the maintenance of the range , he says the rail system for PU attachment requires no specialised tooling . “ This means no small individual components are used that could possibly be lost or damaged during the install . The only wearable parts are the mats themselves and their replacement can be carried out safely by a single operator .”
Construction of the screen ’ s VibroCentric drive removes unnecessary weight while delivering significant acceleration enhanced screening performance . “ It ’ s a fully-sealed drive system
