    When operating a grinding circuit (at Granny Smith) under a wide range of conditions: campaigning very competent underground ore followed by soft oxide, primary versus secondary crushed feed and finally single-stage SAG and conventional SAG, ball mill and pebble crusher (SABC) configurations. Economics changed and a review of the circuit performance including modelling and simulation resulted

  • Optimizing Performance of SABC Comminution Circuit

    If the grind is too fine, the grinding costs will exceed any increment in recovery (and may even reduce recovery depending on the separation process). A standard crushing and grinding circuit is shown in Figure 1. It is commonly referred to as a SABC circuit, for Semi-Autogenous Ball mill Crusher (SABC).
