Ball Charge Ball mills for cement grinding usually operate with a filling degree between 25 and 35 %. The filling degree is defined as the volume of the grinding media (balls) as a percentage of the total mill volume. Since mill speed, liner shape and mill diameter are usually unchangeable parameters, the only adjustment in a mill can be made with filling level and ball size distribution
