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 grind-out.
