· HPGR's can generally accept a coarse feed size up to about 90 mm, provided the roll diameter is sufficiently large (Rylatt and Popplewell, 1999, Morley, 2003, Ntsele and Sauermann, 2007). As a rule of thumb, one should consider that the maximum particle size which would physically/effectively be nipped by the rolls would approximately be 1.75 ...

The application of High Pressure Grinding Roll (HPGR) in comminution circuits is well established in processing cement, diamonds and iron ore. Recently, the application of HPGR has been extended to high-tonnage precious and base metals operations with hard ore. This is due to the HPGR: being more energy-efficient than grinding mills, not requiring steel grinding media, and providing higher ...
