  • Autogenous & Semi-Autogenous Grinding Circuits

    Autogenous Grinding Circuits. When an ore is hard and competent, there is always the possibility that it would make good “pebbles” which could be used for fine grinding media. Different methods that have been tried using combinations of autogenous, semi-autogenous, pebble and/or ball mills. The flowsheets shown are typical of the properties

  • Grinding Mills 911Metallurgist

    Grinding in small plants, as in larger installations, has proven to be the most costly of all unit operations from both capital and operating standpoints. Therefore, grinding deserves the most scrutiny of all operations during the design procedure. A recent survey by a major grinding mill manufacturer reveals that more than 80 autogenous or semi-autogenous mills having between 100 and 1,000
