How to choose the hardness of the steel ball in the ball mill?

In theory, the higher the hardness of the steel ball in the ball mill, the smaller its loss. In fact, some working conditions are not suitable for the use of steel balls with high hardness, especially in the ball mill, the temperature is high and the impact is large, so if the ball hardness of the ball mill is too high, it will greatly increase the rebound between the steel balls. Beating, sliding and collision, thereby weakening the crushing capacity and grinding capacity of the ball mill, and in serious cases, it will cause the surface of the steel ball to flake and break, so we recommend that the steel ball with appropriate hardness should be selected for rough grinding or high impact operations. For fine grinding or low impact operations, high hardness steel balls should be selected.
