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 Grind.
