Gearless mill drives

Our GMD eliminates all mechanical components of a conventional mill drive system, such as ring-gear, pinion, gearbox, coupling, motor shaft and motor bearings: By mounting the rotor poles directly onto the mill, the mill itself becomes the rotor of the gearless motor.

Improved mill control at Lihir Gold Mine in Papua New

Controlling the volumetric filling in the mill is necessary to optimize the mill's throughput rate. Traditionally, volumetric filling has been inferred by controlling to a total mill weight either from bearing pressure or load cells. However, the mill weight is destabilized by two factors, decreasing liner mass and changing charge density.
