A Pilot

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. Get price

The application of a simplified approach to modelling

2009/6/1Breakage 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 Get price
