    2015 1 14   Closed ball mill – cyclone circuits are industry standard and it is recognised that classification efficiency and circulating load both have a major effect on the efficiency of closed circuit grinding. The individual effect of circulating load and classification efficiency is difficult to quantify in practice as

    2013 4 1   The reference point is a conventional ball mill circuit in closed circuit with cyclones operating at 250% circulating load and having 38% of fine material reporting to cyclone underflow, resulting in a classification efficiency of 50%. This efficiency was chosen as an industrial practice average from the data presented in Fig. 6.
