MBE MINERALS TO ENGAGE VISITORS AT ELECTRA MINING AFRICA

MBE Minerals will showcase its product and service offering at Electra Mining Africa 2018, and managing director, Johannes Kottmann, says this will provide an opportunity for existing and new customers to engage with the company’s technical team.

Kottmann says that among the technologies that is seeing increasing demand is the BATAC® jig. The main advantage of this innovative technology is the excellent separation accuracy it offers as well as its relatively small footprint.

“Available at a comparatively low capital cost, this field proven technology delivers higher throughput rates and efficiencies,” he says. “Add to this improved product quality and you begin to understand why it is acknowledged as offering significant economic benefits.”

The company’s ROMJIG® has also proven to be a reliable and economical solution in destoning raw coal. Kottmann says a 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.

Another technology that has attracted global attention is the Pneuflot® flotation technology which Kottmann describes as the flotation technology of the future.

“There are 82 Pneuflot® installations in coal globally and in magnetite and haematite (itabirite) flotation,” he says.

The Pneuflot® flotation cell improves efficiency as well as product quality and recovery, delivering lower capital and operating costs. Its unique design, with no rotating parts, achieves low energy consumption and less wear-and-tear than conventional agitator cells.

The Jones® Wet High Intensity Magnetic Separator (WHIMS) offers a high throughput capability coupled with simple maintenance and lower energy consumption. The robust WHIMS, operated at up to 14 500 Gaus, 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 largest WHIMS plant in the world, outside of Brazil, was installed in the Northern Cape by MBE Minerals SA.

Also available from MBE Minerals SA is the Palla Mill® which is suitable for both wet and dry applications in primary and secondary grinding and for pulverising materials of any hardness. It 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.

MBE Minerals SA also 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. The company’s screens have been operating in the African mining industry for the past 40 years, mainly in the coal, diamond and iron ore sectors.

With products for sizing, scalping, dewatering and media recovery, the company’s screens feature an innovative side plate mounted drive, making them lighter than those using vibrator motors. MBE Minerals SA 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.

MBE MINERALS FOCUSED ON SUPPORT FOR OPTIMAL PERFORMANCE

With mining operations remaining under pressure to optimise plants, original equipment manufacturers (OEMs) and suppliers must be more dynamic and focused in terms of their overall market offering.

This is the message from Johannes Kottmann, managing director of MBE Minerals SA, who says that the company’s strong relationship with and understanding of its customers’ operations allows it to provide optimum value support and services, all of which is aimed at ensuring that operations perform optimally.

MBE Minerals’ support options are customised to suit specific customer requirements and can range from basic maintenance contracts, which would typically include on-site service personnel, and can extend to consignment stock facilities and progress right up to comprehensive Service Level Agreements (SLAs). At this level, support is provided through fully fledged regional service centres capable of undertaking ongoing equipment condition monitoring, maintenance and service support.

Customers are able to leverage the expertise and in-depth experience MBE Minerals SA has acquired across the full spectrum of services to a large footprint of customers. “With an OEM supporting the equipment in the plant directly, it is possible to implement efficiency improvements as a result of ongoing input and interaction with the plant personnel. In addition to this, training is undertaken that benefits the plant personnel both in terms of operator needs and maintenance,” Kottmann says.

The maintenance of equipment in mineral processing plants is equally as important as its optimum functioning and a multi-disciplined approach needs to be instituted when designing a plant. Kottmann maintains that OEMs should be tasked with the continued and consistent maintenance of equipment in the plant to ensure that it is carried out cost effectively and downtime is reduced.

“We have seen a trend developing within the industry whereby customers are moving away from maintaining plants in-house to an SLA or life-cycle contract with the OEM. This implies that the manufacturer is not only selling a piece of equipment but is also supplying the customer with a comprehensive maintenance plan,” Kottmann explains.

“Coupled with this is the importance of the OEM’s location in relation to its customer’s operations, and we currently operate a fully-fledged service centre in Kathu in the Northern Cape to cater for these iron ore and manganese operations and in Middleburg to service various customers in the coalfields,” Kottmann says. As a result, the MBE Minerals teams have developed first-hand knowledge of how its equipment is operating within the various plants, enabling application-specific design improvements that result in an enhancement in the operational life and efficiency of the equipment.

“Our locality in close proximity to our customers also allows us to provide a rapid response technical assistance and maintenance service. We maintain a substantial stockholding of requisite parts as determined by the customer base’s needs and we can offer both on- and off-site service. From an OEM perspective, we will ensure that the correct parts are installed according to specification, and that the equipment operates within its design limits, to ensure maximised throughput and minimised downtime,” Kottmann concluded.
