Autogenous mill is a self-grinding mill which is used in breakage of larger rocks. SAG (Semi-Autogenous Grinding) mill is an autogenous mill which uses grindingballs, it is similar toballmill but has large diameter and short length. Vertical mill is used in grindingmaterialat smaller particle sizes, which is used afterballmill.
