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.
