of autogenous, semi-autogenous and ball mill grinding circuits6. Schnatz carried out a huge test program on a semi-industrial ball mill which operates in a closed circuit. He evaluated performance of a ball mill circuit by varying the LD ratio, ball charge filling ratio, ball size and residence time and determined their optimum value7.
The change from a SAG mill to an HPGR in primary grinding results in a lower overall power consumption the comminution circuit. In comparison to using staged crushing as ball mill feed prepara-tion, replacing the tertiary circuit with an HPGR frees up ball mill capacity or reduces the size of the ball mills and grinding media consumption.
