A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

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.

The ball mill was being relined as part of a planned shutdown. The inching operation had been successfully completed 45 times during this shutdown. The operator was manually controlling the repositioning of the ball mill drum by driving the electric inching drive motor through the 700 to 1 ratio gearbox. When the drum was in position, the operator
The SAG inching drive did work hardest at this point, but nowhere near the difficulty the ball mill inching drive had on the ball mill under similar circumstances. Effect on operating practice change with the new liners: The concern was that the expensive set of new liners would be damaged upon startup due to operator unfamiliarity running ...
