These mills are equipped with grinding media composed of wolfram carbide or steel. Ball mills rotate around a horizontal axis,partially filled with the material to be ground plus the grinding medium. The balls rotate with high energy inside a drum and then fall on the solid with gravity force and crush the solid into nano crystallites.

May 22, 2019The ball mill consists of a metal cylinder and a ball. The working principle is that when the cylinder is rotated, the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force. At a certain height, it will automatically fall and impact
