As the mill rotates, the feed material is lifted by the shell lining, and due to gravity, it falls down, resulting in material impact and breakage. This self-grinding process occurs in autogenous mills. When ore properties are inadequate for autogenous grinding, the addition of steel grinding media compensates in semi-autogenous mills.
