Ball mills Ball mills vary in their details and size but the basic design consists of a horizontal hollow cylinder, with an abrasion-resistant interior, that rotates about its central axis. The grinding is performed by stone, metal or rubber balls that are free to move in the cylinder (Figure 1). The balls form around 40 to 45 percent of the load.

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.
These mills typically grind ROM ore in a single stage. A large example of such a mill was converted from a single-stage milling application to a semi autogenous ball-mill-crushing circuit, and the application is well described. This refers to high-aspect AG/SAG mills. Ball Charge Motion inside a SAG Mill. With a higher density mill charge.
