  • Mill (grinding) Wikipedia

    Autogenous mill Autogenous or autogenic mills are socalled due to the selfgrinding of the ore: a rotating drum throws larger rocks of ore in a cascading motion which causes impact breakage of larger rocks and compressive grinding of finer particles.

  • AG Autogenous Grinding Mineral Processing Metallurgy

    AG Autogenous Grinding. The main source of reduction comes from the impact of the rock falling on rock. The mill has only twenty five to thirty percent of its volume taken up with ore. With that diameter of mill the cascade point is very high from the toe of the load. Which is the impact zone for the media.
