How Ball Mill work? Ball mill is a grinder for reducing hard materials to powder. A ball mill grinds material by rotating a cylinder with steel grinding balls/ceramic balls causing the balls to fall back into the cylinder and onto the material to be ground. The cylinder rotates at a relatively slow speed, allowing the balls to cascade through ...
