  • Closed circuit ball mill – Basics revisited ScienceDirect

    Based on experience acquired over the years and the investigative work conducted by FC 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  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 these two parameters are inherently interrelated Even though mill capacity increases with circulating load, VALIDATION OF A CLOSED CIRCUIT BALL MILL MODEL Ball MillClosed Circuit Type The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultrafine particles, so ball mills operate most efficiently by making a coarse product, the fine fractions of this then are being separated, and the coarse part being returned to the mill Ball MillClosed Circuit Type at Rs /unit
