The ball mill breakage rates are for a feed rate of 400 g/min and have been adjusted to the same media load/unit length and the same holdup weight as for the rod mill. The differences between the breakage rates in the ball mill and in the rod mill at 450 g/min total feed rate may be attributed directly to the different grinding media.
