The cost of edge drive is low, but the pinion needs to be replaced every 2-5 years. Edge drive is mainly used in coal mills and mills with small power. The girth gear(big ring gear) and pinion are the key of the edge transmission device. Their reliable operation is directly related to the stable production of the mill.

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

For a spur gear, the dimension over two pins is very simple and ideal. This is because if the gear is hobbed, gauge balls might fall into the scallops in one measurement or rest on the high point in another whereas gauge pins always rest on the high points of the scallops. This makes for more consistent measurements.

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.
