· The net effect is an increase in rock mass and the feed rate to the mill must be decreased appropriately to maintain rock-to-ball ratio. On the other hand when the ore is soft the field of breakage reduces the ore size rapidly and hence the rock mass decreases. To sustain a set rock mass the feed rate must be increased.
