May 02, 2018 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

Ball Mill Drives These large coal crushing drive systems are usually rotated by motor-driven gearing. A typical application consists of a motor-driven primary single-stage reducer that, through a flexible coupling, drives a large open pinion which in turn, meshes with a large ball mill ring (girth) gear that is attached directly to the ball mill.
