#### 10 Ways to Improve the Grinding Efficiency of Your Ball

2. More crushing and less grinding to reduce the feed size into mill. The larger feed size, the more work that the ball mill needs to do on the ore. To achieve the specified grinding fineness, the workload of ball mill will be increased inevitably, and then, the energy consumption and power consumption will be increased accordingly.Magnetic Separation Techniques to Improve Grinding ,However, the total mill power consumption dropped 8% from an average of 7600 kW to 7000 kW. The mill work index dropped 10 percent from an average of 5.5 kW-hr/T to 5.0 kW-hr/T. Conclusions This represents a current view of the effects of grinding ball fragments in the milling circuit and the impact on the crushing and grinding circuit.
