Energy and Cost Comparisons of HPGRbased Circuits | E MJ
Figure 2—HPGR ballmill circuit. To determine whether the novel HPGRstirred mill circuit arrangement could achieve energy savings in comparison to conventional SAG millbased circuits, a pilotscale study was conducted to compare the energy requirements of the existing circuit at the Huckleberry mine to two alternative circuits: an HPGRball mill circuit and a novel HPGRstirred mill circuit.

Improved characterisation of ball milling energy ...
Multiple tradeoff studies comparing different comminution circuit options have estimated that HPGR circuits can offer energy savings of between 11 and 32 per cent compared with SAG milling circuits (Davaanyam et al., 2015). The confinedbed breakage mechanism employed by the HPGR requires less energy to achieve the same degree of size reduction as SAG milling.
