MBE Minerals, which is celebrating 40 years of supplying minerals beneficiation technology to the African mining sector, will be participating at Electra Mining Africa (EMA). The company will be exhibiting a number of its technologies, and will have technically competent personnel be on hand to answer any questions.
Among its various products, MBE’s stand will showcase Pneuflot flotation technology and BATAC jig technology.
Pneuflot flotation cells improves product quality and recovery, delivering lower capital and operating costs, as well as significantly lower wear costs and higher efficiencies. They feature a unique design with no rotating parts, achieve low energy consumption and less wear-and-tear than conventional agitator cells.
According to Johannes Kottmann, managing director of MBE Minerals, the company’s BATAC jig technology has been field-proven through extensive and diverse test work to deliver higher efficiency, huge economic benefits, better product quality, better machine availability and higher throughput rates. The main advantages are its excellent separation accuracy, its relatively small footprint and comparatively low capital cost.
“Our ROMJIG has proved particularly suitable as a reliable and economical solution in destoning raw coal. The lower percentage of refuse in the washery feed means reduced wear on machinery and transporting equipment, less grain degradation, less dust and slurry and reduced consumption of flocculation and flotation agents in downstream fines recovery circuits,” Kottmann says.
Another product on display at EMA is the robust Jones Wet High Intensity Magnetic Separator (WHIMS), operated at up to 14 500 Gaus. It offers a high throughput capability coupled with simple maintenance and lower energy consumption, and is ideally suited to treating feebly magnetic minerals with a particle range from 20 microns up to 1.5 mm with unit throughput capacities from 500 kg/h up to 250 tph.
The Permos Medium Intensity Magnetic Separator (MIMS) drum type unit from MBE Minerals is suitable for materials which can be attracted by a field strength of between 2 000 and 5 000 Gaus. Kottmann says there are designs for both dry and wet feeding available.
Similarly, the Palla Mill offers the flexibility of being suitable for wet and dry applications in primary and secondary grinding and for pulverising materials of any hardness. “This technology has a major advantage over other machines as it is capable of grinding more than 100 different materials, including a range of minerals and commodities previously considered unviable due to the costs involved,” Kottmann adds.
The company manufactures a variety of vibrating screens, available up to 3.6 m in width and 6.75 m in length, in single or double deck configuration and in either circular or linear motion. With products for sizing, scalping, dewatering and media recovery, the screens feature an innovative side plate mounted drive, making them lighter than those using vibrator motors.
MBE Minerals also supplies screens with vibrator motors where required, while its resonance screens offer the benefit of low power consumption. Each screen is designed with sound mechanical features including vibration damping, side plates, cross members and the appropriate feed and discharge chutes. All types of screening surfaces can be accommodated.
