  • Autogenous Grinding Article about Autogenous Grinding by

    In autogenous grinding a distinction is made between ore and ore-pebble grinding. Ore grinding is carried out in mills with a large diameter (up to 12 m) and short length (the ratio of diameter to length is approximately 3). Ore with pieces having dimensions up to 300 mm (sometimes up to 600 mm) is loaded into the mill.
