Mill capacity increases linearly with increasing ball load for both ball sizes within the considered range. The 30 mm ball draws slightly more power as J increases from 11 to 16% but the gain in capacity is much more. In fact for an increase in J from 11 to 16% (i.e. 45% increase), power draw increase is 31%, while capacity increases by 51%.
