Kwatani registers global mining demand for vibrating equipment

Kwatani’s vibrating screens and feeders are continuing to find a market in the mining industry, with a number of orders recently secured from diamond, coal, zinc and platinum operations.

The company’s custom engineered products are now in some of the world’s largest mines, and many customers have standardised on their screens to ensure lowest cost of ownership and high performance, according to General Manager, Sales and Service, Jan Schoepflin.

“While our base and core market are in Africa, the global demand for Kwatani products has grown rapidly. A leading diamond mining company in Russia is very pleased with Kwatani screens at their newest operation and specified Kwatani for future projects,” Schoepflin says.

In another order from a large diamond operation, this time in South Africa, the customer replaced the last of its competitor screens with a Kwatani unit. Schoepflin says this is because it has enjoyed years without unplanned stoppages by using Kwatani screens.

At a local brownfield diamond expansion project, the company’s multi-slope banana screens were matched to the available plant footprint, raising throughput from 250 t/h to 500 t/h and, later, breaking the mine’s tonnage record.

“While screening in heavy minerals is Kwatani’s stronghold, the company has moved extensively into coal, supplying the country’s (South Africa’s) leading coal producer with no fewer than 45 items of large screening equipment, including out-sized 4.3-m-wide units,” the company said.

Other recent coal-related orders included run-of-mine screens for a medium-sized coal mine in Mpumalanga, South Africa. Again, competitor equipment was replaced by custom designed screens with optimised deck angles, which significantly increased tonnage, according to the company.

“The positive results achieved with the Kwatani equipment also led to additional orders for the mine’s expansion,” Kwatani said.

For world largest zinc mine, Kwatani was contracted to supply all the screens, while, at Africa’s largest iron ore mine, the company recently completed two projects, renewing existing equipment with updated solutions and replacing 24 items of competitor equipment.

“The platinum sector is also keeping Kwatani busy, not just in South Africa but over the border in Zimbabwe too,” Kwatani says. A recent turnkey solution focused on platinum by-product chromite, where the company supplied a complete solution which included feeder, dryer and screen to treat chromite of 45 micron size at 15 t/h.

Schoepflin said: “Our screens have been a popular choice for modular gold plants going to West Africa as well as Central and South America. We also supplied to two of Africa’s largest copper producers in Zambia, to a tanzanite producer in Tanzania, and repeat orders to a manganese mine in Ghana.”
