grinding ball mill performance

The energy specific grinding rate of the coarse material in the ball mill can then be defined as follows The mill specific grinding rate reflects both the efficiency of the mill environment in breaking the coarse particles as well as the grindability characteristic of the ore over the particular size reduction range
