A ball mill operates by rotating a cylinder with steel or ceramic balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation of the cylinder is typically between 4 to 20 revolutions per minute, depending on the diameter of the mill. The larger the diameter, the slower the rotation.
