The hardness of the steel ball is not necessarily the higher the better.

As we known, the harder the grinding balls in the ball mill are, the less they will be worn. However, if the wear of the grinding balls is too high, it will cause the high chrome grinding balls to rebound, resulting in energy loss during the jumping process, which will affect the crushing capacity of the ball mill. Moreover, it will also lead to the sliding between the balls, which will affect the grinding capacity of the ball mill. At the same time, the severe sliding between the balls weakens the grinding effect on the materials. Therefore, only grinding balls with an appropriate hardness can ensure the production efficiency of the mineral processing production line.
