    Quantifying the energy efficiency of fine grinding

    In the first survey the ball mill was underperforming due to the low density in the mill, which was rectified in the second survey. The ball mill was grinding to a P 80 of 50 to 70 m, therefore the traditional marker size (75 m) was not applicable, and this can be seen by the increase in SSE for coarser sizes as the marker size approached P ...
