## Relation between ball mill dia and capacity

To take a closer look at the relationship between the power draw and the ball diameter, Figure 4 below was plotted using data from 4 mill revolutions for which the milling duration was 4 seconds. As could be seen from the Figure 4, there seemed to be no trend for the power draw with regards to the ball diameter
