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.

Conventional ball mills rotate the mill body (a horizontal cylinder), tumbling both rock and metallic balls. Stirred mills use an internal auger to agitate the feedstock (ore which is fed into the mill as a slurry) and grinding media (sand, ceramic balls), which produces finer, more uniform grind sizes with reduced energy consumption.
