  • Closed circuit ball mill Basics revisited ScienceDirect

    1/4/2013· Based on experience acquired over the years and the investigative work conducted by F.C. Bond, it was established that the optimum circulating load for a closed ball mill cyclone circuit is around 250%. This value is used as guideline for the design of new circuits as well as to assess the performance of existing circuits.

    IntroductionOver the years, ball mill circuits closed with cyclones have become an industry standard, and since the early days, it has been recognised that classification efficiency and circulating load both have a major effect on the efficiency of closed circuit grinding (i.e. its capacity to produce the desired final product).

    It can be observed that for a ball mill circuit closed with cyclones, circuit relative capacity is not expected to increase significantly by increasing circulating load from 250% to 600%. This is because of the reduction in classification efficiency from 50% to 30% as calculated by Eq.
