  • The working principle of ball millMeetyou Carbide

    The 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 and grind the material in the cylinder to grind
