### mining industry: what is the difference of ball mill

most mills used in mining rely on impact to breakdown rock to a suitable size for downstream processing. the impact can be rock on rock such as in an autogenous grinding (ag) mill, rock and a small ball charge (~10%), used in semi autogenous grinding (sag) mills, balls of various sizes in ball mills and less commonly these days, steel rods in rod mills.
