At this year’s Electra Mining exhibition, MBE Minerals South Africa – formerly Humboldt Wedag – will exhibit static scale models showcasing key elements of its broad range of technology.These will include its Pneuflot flotation, Batac jig, Romjig, Jones Wet High Intensity Magnetic Separator (WHIMS), Permos (LIMS), a Palla Vibrating Mill, Teska HMS Separator and a wide variety of screens and feeders. In 2010, Indian turnkey engineering giant McNally Bharat Engineering (MBE) acquired German-based Humboldt Wedag Coal and Minerals Technology, including its South African subsidiary, and in the two years subsequent to this acquisition, MBE Minerals has made excellent headway in aligning its growth strategies with that of its new holding company. The MD of MBE Minerals SA, Johannes Kottmann, says the acquisition has expanded his company’s proprietary technology ownership, ideally positioning it to expand its presence across the entire SADC region through the introduction of new equipment, and technology and partnerships. “We want to evolve into a complete technical solutions package provider, from technology creation to product manufacture and installation, along with all associated ancillary equipment. We’re much more than an equipment distributor – we want to be recognised as a fully fledged process engineering company,” Kottmann says. The company’s Pneuflot technology is coming to the fore worldwide as a flotation technology of the future, rapidly surpassing the popularity of conventional technology. The Pneuflot machine flotation cell improves product quality and the recovery, delivering lower capex and opex, as well as significantly lower wear costs and higher efficiencies.
Its 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 prime advantages of this system are its excellent separation accuracy, its relatively small size and comparatively low capital cost. Accuracy is achieved through electronic control of the air pulse generator and sensing of the thickness and densities of the material layers being separated.Since its introduction to the marketplace, MBE Minerals SA’s Romjig has proved particularly suitable as a reliable and economical solution in processing coal. Extensive testing overseas has shown this jig to operate with an efficiency (imperfection) of I=0.08 to 0.1. Research indicates an overall reduction in the stone handled, as well as advantages resulting from the lower percentage of refuse in the washery feed. These include reduced wear on machinery and transporting equipment, less grain degradation, less dust and slurry, and reduced consumption on flocculation and flotation agents in downstream fines recovery circuits. The robust Jones WHIMS offers a high throughput capability coupled with simple maintenance and lower energy consumption. The Jones is ideally suited to treating feebly magnetic minerals with a particle range from 20 microns up to 1 mm. Also on display as a static scale model, 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. “The Palla Mill has a major advantage over other machines of this type 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 says. “Add to this ultra-fine grinding at maximum production with the lowest expenditure on installation, grinding media and maintenance, and it becomes obvious why this vibrating mill has become a standard internationally,” he says.
