Figures 5 and 6 respectively. Accurate measurements of the ball filling can only be made after the mill is ground out. In this case the mill is operated with the feed turned off until all of the ore has exited the mill. Measurements of the ball level within the mill can then be made. Figure 7 shows an example of the balls in a mill after a

The processing capacity of the ball mill increases with the increase of the filling rate of the steel ball. It increases the probability of grinding the ore and the self-grinding effect. When the ball filling rate is 45%, the ball mill load is the largest, and when it exceeds 45%, the load is greatly reduced as the filling rate increases
