Control Feed Size. The particle size of the material entering the ball mill is controlled between 2515 mm (the diameter of the ball mill is different for different feed sizes). Excessive rules will cause the ball mill to have too much fine material during the grinding process and cannot achieve the friction between the material and the material.
