The planetary ball mill has a working principle of impact and friction. The planetary ball mill is equipped with four ball mill tanks and the sun wheel that rotates on its axis. The ball mill tanks also revolve around the sun wheel in a planetary fashion, hence the name planetary ball mill. The grinding jars do rotate in an orbit around the center.

Ball mill. A ball mill, a type of crusher, is a cylindrical device used to grind chemicals or mix compositions. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium, ideally non sparking milling media like lead balls. An internal cascading effect reduces the material to a fine powder.
