Planetary ball mills are perhaps the most commonly used ball mills in laboratories for the sample preparation of soft to hard, brittle and fibrous materials. The name of this mill type derives from its unique kinematics: the grinding bowls, which are mounted on the rotating sun disk, rotate in the opposite direction around the centre of this disk.

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.
