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-on-shell impacts just above the charge toe, owing to the risk of ball-on-liner damage and excessive metal flow. In fixed-speed mills, this may be achieved by increasing charge volume; in variable speed mills, this may be achieved by reducing mill speed; and in both cases this may be achieved by design by increasing the lifter face angle.

The creeping mode has the same application as the inching mode, namely to position the mill to a certain angle for liner change. During inching mode, the mill operates at a low speed of 1.2 rpm. This is about 10% of the normal operating speed, but still too fast to follow the mill with the eyes and to position the mill with start/stop signals.
