• Autogenous Grinding Mining Fundamentals

    30.12.2013· Autogenous grinding is a process of grinding ore in a rotating cylinder, using large pieces of the same ore. Autogenous mills operate mechanically like ball mills; however, the media used for grinding differs. Simply put, in autogenous grinding, the media is also the material that is being ground, whereas in other milling methods steel or porcelain balls are used as media.

    AMIT 135: Lesson 6 Grinding Circuit Mining Mill

    Grinding is a powdering or pulverizing process using the rock mechanical forces of impaction and attrition. The two main objectives for a grinding process are: To liberate individual minerals trapped in rock crystals (ores) and thereby open up for a subsequent enrichment in the form of separation.

    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.
