A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

Within the jar are placed several ball bearings and the sample of interest. As the jar rotates, the balls grind around the outside, imparting shear forces to the sample before reaching a point in the revolution where they pulloff and impact on the sample on the opposite side. Mixer mills on the other hand house the jars in a horizontal position.

1. Introduction. Planetary ball mills provide high energy density due to the superimposed effect of two centrifugal fields produced by the rotation of the supporting disc and the rotation of the vials around its own axis in the opposite direction [1].During operation, the grinding balls execute motion paths that result in frictional and impact effects.
