Global mining drives and motors major WEG says its equipment has been selected for some major projects Metso Outotec is carrying out in mineral processing plants in Brazil. The equipment package provided by WEG includes two vertical three-phase induction motors of the Master line, models MGI630 (2,300 kW) and MGI560 (1,600 kW), a medium voltage frequency inverter model MVW3000 and seven 150 hp motors.

WEG said the orders are focused on the operation of the main vertical mills at plants in Brazil. Metso Outotec says its Vertimills provide superior efficiency with high throughputs and a low plant footprint. “Grind efficiency, reduced media consumption, lower installation cost, minimal maintenance, and minimal liner wear make Vertimill® the lowest total cost of ownership in many applications, substantially improving the profitability of concentrators. Mechanically, Vertimill is a simple machine with an agitating screw suspended into the grinding chamber, supported by spherical roller bearings and driven by a fixed speed motor through a planetary gearbox. The capacity of each unit size is relative to the required power input for the intended grind, however, mills have been operated with throughputs exceeding 500 t/h.”

This supply WEG says “reinforces the expertise and quality of WEG products for the mining segment and strengthens the partnership with Metso Outotec, an important player in the market. In addition, the choice of WEG equipment guarantees all the technical and after-sales assistance necessary for the greatest efficiency of the solutions.”
