speed for ball mills

A Ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation
