Closed circuit ball mill – Basics revisited
The relative capacity model predictions (compared to the reference point of 250% circulating load and 50% classification efficiency) are presented in Fig. 7. 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%.
