Schematic drawing of an attrition ball mill. The attrition mill agitator rotates at speeds ranging from 60 rpm for production units to 300 rpm for laboratory units and uses media that range from 3 to 6 mm while ball mills use large grinding media, usually 12 mm or larger, and run at low rotational speeds of 10–50 rpm.

components that could pose a concern to the life of a motor include the bearings, the brushes, and the commutator. The brushes and the commutator create the electrical connection in brush type motors; as the motor runs these components tend to wear down. Generally, in limited use applications, a brush type motor will be an economical choice.
