Grinding to the core

Reliable and efficient drive solutions for horizontal mills

Horizontal mill pinion drives are widely used in the mining industry to grind materials to a requested size. If the equipment is operating at optimum efficiency, this has positive impact on production and operating economics. Drive solutions are needed for speed and torque control. Among the resulting operational benefits, longer maintenance intervals and lower energy costs are the most important. Owners need drive solutions that improve speed control, lengthen maintenance intervals, and lower energy costs.
