Energy and Cost Comparisons of HPGR-based Circuits | E & …

Figure 2—HPGR ball-mill circuit. To determine whether the novel HPGR-stirred mill circuit arrangement could achieve energy savings in comparison to conventional SAG mill-based circuits, a pilot-scale study was conducted to compare the energy requirements of the existing circuit at the Huckleberry mine to two alternative circuits: an HPGR-ball mill circuit and a novel HPGR-stirred mill circuit.

The application of a simplified approach to modelling ...

01-06-2009· Breakage in an HPGR is fundamentally different to a tumbling or stirred media mill in that the relationship between grind size and specific energy input is highly nonlinear. This arises from the fact that as material passes through the rolls, the void volume in the particulate bed becomes progressively smaller, resulting in disproportionately greater dissipation of energy in the form of ...

A Pilot-Scale Examination of a High Pressure Grinding Roll ...

The HPGR / stirred mill circuit required considerably more pilot-scale testing than the previous two circuits, since very few operating examples could be found in the literature. The results of pilot-scale testing determined the appropriate layout for the two-stage HPGR circuit and provided the corresponding specific energy consumption for circuit energy summation.
