    Then the circulating load ratio is equal to 'A' divided by 'B', the number of passes through the mill needed to generate the total amount of new circuit product. Example: A ball mill circuit product (cyclone overflow) contains 80% passing 75 um (200 mesh). The circuit feed (from the previous stage of size reduction) contains 20% passing 75 um.

  • circulating load calculation in closed circuit ball mill

    Circulating Load Calculation Formula. Why have a large circulation load:. If a product all finer than a certain critical size is required, the capacity of the ball mill is increased considerably by using it in closed circuit with a classifier and this increase is made still greater by increasing the circulating load in between the ball mill and the classifier (Fig. 70).

  • circulating load formula in ball mill

     · The circulating loads generated in a typical ball mill cyclone circuit contain a small fraction of bypassed fines. The concept that high circulating loads will result in overgrinding can be refuted by regarding increases in circulating load in the same vein as multistage grinding. That is, for every incremental increase in circulating load of ...

     · A high circulating load at a fixed product size means lower energy consumption, but excessive circulating loads can result in the mill, the classifier or the pump overloading. Hence there is an upper limit to the mill feed rate. In other words, the grinding efficiency improves with increasing circulating load until the mill overload condition is reached and the mill .
