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).
