Inching drive: 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 ...
Ball mill charge contains a significant amount of steel balls and can become extremely heavy. For example, a large 24 foot ( m) diameter ball mill charge typically weighs around 2 million lbs (907 tons). ... If the mill is equipped with an inching drive, rotating the mill slowly will ensure the breakup of the frozen charge. If an inching ...

Inching is used in various applications such as conveyor belts, and ball mills. Inching involves short thrust of motions at reduced power. A ball mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground.
The inching drive, also known as a barring or auxiliary drive, is an important component of any mill or kiln installation. It is used for maintenance and inspection purposes, as well as an emergency auxiliary drive to keep kilns rotating when the main motor fails.

general, the bigger the mill diameter, the lower are the mill operating and critical speeds. Thus, for larger mills the number of poles will increase. As a result, the number of poles can vary from 48 to 72 poles (Fig. 3.) with typical mill speed requirements of about 10 rpm for larger SAG mills and about 15 rpm for smaller ball mills. Figure 3.
