Description: 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 181m, therefore the traditional marker size 75 181m was not applicable, and this can be seen by the increase in SSE for coarser sizes as the marker size approached P ...
