Autogenous grinding mills (AG mills)

Autogenous mills, or AG mills, can accomplish the same size reduction work as two or three stages of crushing and screening. Often used in grinding at modern mineral processing plants, AG mills reduce the material directly to the desired final size or prepare it for the following grinding stages.

How it Works Crushers, Grinding Mills and Pulverizers

Autogenous grinding (AG) and semiautogenous grinding (SAG) mills use the material to be ground as the grinding media. Autogenous grinding mills use larger rocks to impact and break smaller rocks as the mill rotates. Semiautogenous mills are basically the same autogenous mills, but with the addition of balls, similar to those in ball mills.
