Inching Drive Backstops/Brake System. for Ball Mills, Kiln Drives, and Incinerator Applications Disc Brake Method The inching drive is an auxiliary drive for rotating the ball mill when maintenance work is done on the mill. It consists of an electric motor and gear reducer.
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
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.
