What is SAG Semi-AutoGenous Grinding and How it works

Autogenous and semi-autogenous mills are typically operated at slightly higher speeds than ball mills of the same diameter. These purpose of a grinding circuit is to reduce the size of feed material to a size sultable for either a final product or for further processing. Further processing may involve a leach. Flotation, gravity separation or magnetic separation. Of thee processes, flotation, gravityMill (grinding) - Wikipedia,Autogenous or autogenic mills are so-called due to the self-grinding 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. It is similar in operation to a SAG mill as described below but does not use steel balls in the mill. Also known as ROM or "Run Of Mine" grinding.AG Autogenous Grinding - YouTube,Animation of the grinding action inside an AG Autogenous Grinding Mill.

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.
