hardness of mill grinding balls

The hardness of grinding media ball how to choose balls

But for the productivity of the ball mill, the productivity increases with the increase of the hardness of the ball in a certain range, but when the hardness exceeds a certain range, the productivity of the mill decreases. When the hardness of grinding media ball is too high, there are two unfavorable reasons for grinding
