Autogenous grinding has two advantages, (1) it reduces metal wear and (2) the use of large ore particles as grinding media means that the need for secondary and tertiary crushing stages is reduced or eliminated. AG and SAG mills are available for both wet and dry grinding. The diameter of AG and SAG mills is normally two to three times the length.
