crushing and grinding oxidation

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.

Crusher - Wikipedia

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
