    2004-12-10  The optimal ball charge filling ratio for Combi-ball mills is supposed to be less too. Shoji et al. (1982) investigated the influence of the ball charge filling ratio on the specific power consumption for the grinding of quartz sand. They found a flat minimum at a ball charge filling ratio of about 15%.

    The L/D ratio of the ball mill was varied in four steps of 1.75, 2.1, 2.79 and 3.49, and the ball charge filling ratio was varied in three steps of 15%, 20% and 25%. The experiments clearly indicated that the optimal L/D ratio and the optimal ball charge filling ratio are different for each feed fineness.
