EFFECTS OF GRINDING MEDIA SHAPES ON BALL MILL

Considering that worn balls in an industrial mill charge constitute about 15 to 40 percent and that the highest difference in breakage rate observed being nine percent for purely one shape charge it is very doubtful whether it is worthwhile in attempting to develop techniques for removing worn balls from the mill
