  • How it Works Crushers Grinding Mills and Pulverizers

    Autogenous grinding (AG) and semi-autogenous 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. Semi-autogenous mills are basically the same autogenous mills but with the addition of balls similar to those in ball mills.
