The mill jars are rotated with the aid of a jar rolling mill, which has two rollers to support and rotate the jars at the proper speed. The milling jar is half filled with grinding media or balls from ¼" to 1" and as the mill rotates the solids are trapped between the ball and are milled down to as little as 1 micron by the cascading and tumbling action of the ball charge.

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 120 percent of the normal drive torque.
