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% ( 45% increase), power draw increase is 31%, while capacity increases by 51%. For the 50 mm balls the respective increase in power and capacity is 28% and 42%.

Operating principle of the coal mill. Fig. 1 shows the structure of a duplex inlet and outlet ball mill. The system is equivalent to two parallel cylinders joined together in one ball mill to achieve high milling efficiency. Milling work is carried out by the collision, squeezing and grinding of the steel balls inside the mill.
