Ball Mill Drives - Mineral Processing Metallurgy

2019-10-15  V-BELT Ball Mill DRIVE V-belt or poly-V drives are generally used on grinding mills consuming 350 HP or less. Where power exceeds this, drives become so large and motors become special, resulting in an uneconomical application. Generally the driven mill sheave is of split hub construction to facilitate field assembly.

What is an inching drive? - motioncontroltips

An inching drive is used as an auxiliary system to the main drive for a large machine such as a ball mill, industrial kiln, conveyor, or elevator. Its purpose is to turn the equipment at a speed slower than the normal operating speed — typically 1 to 2 rpm, although fractional rpms are also common — and to do so at high torque — typically
