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.

Ball bearings are rolling element bearings that use balls to separate the bearing races and provide smooth, low friction motion in rotary applications. Ball bearings are manufactured in hundreds of sizes, from the ultrasmall mm diameter bearing for use with miniaturized medical devices and micromotors, to bearings over 15 feet in diameter for use in heavy equipment.
