ball and sag mill circuits

ball and sag mill circuits

It is commonly referred to as a SABCcircuit, for Semi-AutogenousBall millCrusher (SABC). Thiscircuitshows a semi-autogenous grinding (SAG)/ball mill circuitwhere both grindingmillsare in closedcircuit, with theSAG millclosed with a crusher to control the amount of ‘critical size’ material in thecircuit.
