South African screens ordered by Australian mine

MBE Minerals reports it has secured yet another export contract from Australia for the supply of its custom engineered and manufactured heavy duty vibrating screens. The South African original equipment man- ufacturer (OEM) attributes the ongoing successes being achieved in Australia to its ability to produce vibrating screens that offer reliable operation in themining sector. HeinzMittermaier, EngineeringManager at MBE Minerals, says that the recent con-

customer’s needs have been met. “The strength of this customer relationship and collaboration is underpinned by our ability to accurately interpret the specific needs of an individual customer and to meet these while being on a different continent,” Mittermaier says. The MBE Minerals screens being sup- plied are 2,4 by 4,5 m and have been optimised for this iron ore operation. The design makes use of the benefit of low power consumption for the movement of large masses which is only provided by the resonance system. In addition to the already low power consumption of the vibrating screen, the life expectancy of the screen box has been improved signifi- cantly by combining state-of-the-art wear resistance components with the reliably designed heavy duty screen structure. MBE Minerals SA, tel (+27 11) 397-4660 ahead of our competitors,” he says. With less time and money being spent on changing screens while separating excavated materials, Dlamini adds that the Aury Africa woven wire screen cloths have improved productivity at the Olifantsfontein quarry. “This also enables us to extract, sort and deliver our superior quality aggregates to our customer base in the quickest turn- around times.” Dlamini believes that Aury Africa’s after-sales service and technical support is unrivalled. “A new screen cloth with new screen opening size, wire diameter, and attachment typically takes around 15 days. In some cases, wemay require the screen in con- siderably shorter timeframes, due to customer demands, and Aury Africa representatives are

tract underpins South African OEMs’ capabilities in producing equipment for demanding applications in the mining sec- tor, and particularly those in a First World country like Australia. The screens form part of an ongoing replacement cycle at an Australian iron ore mine and Mittermaier says that with its extensive experience in such applications on the African continent, MBE Minerals has been able to optimise its screen design. “Those screens already supplied pre- viously have proven successful in terms of throughput tonnages and operational reliability and the customer has chosen to continue with this optimised product.” But what is of even greater impor- tance is that MBE Minerals has been able to leverage not only its engineering and manufacturing capability but also com- munication technology to ensure that the upgrade, which involved the reposition- ing of the whole primary jaw crusher to increase tonnages. As a result of this capital- intensive investment, AfriSam Production Superintendent Joseph Dlamini notes that it is essential for the operation to minimise excessive costs on plant consumables. “The previous supplier’s wire mesh lasted about 800 hours before it needed to be changed. Since switching to the Aury Africa range, changing intervals have sig- nificantly improved to 850 hours, which equates to approximately five more days of screening per screen cloth. It takes many hours to change a screen due to weight and dimensions. Since we spend less time removing Aury Africa screens, we can capi- talise on our investment, which places us

Quarry sold on Aury’s woven wire screens The AfriSam Olifantsfontein ready-mix and aggregate quarry in Gauteng has been making use of Aury Africa woven wire screens since 2014. The screens are claimed to be more cost-effective and to last up to five days longer than competitor products, thereby minimising downtime and ensur- ing substantial long-term savings.
