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 ...
Excess capacity in the HPGR circuit will now be used to produce a ball mill feed product of approximately P 80 1/8" (nominally 3.5 mm), a 42% reduction from past .
Comparison of open and closed circuit HPGR application on. Within this study effect of open and closed circuit HPGR applications on dry grinding circuit performance was examined For this purpose sampling studies around three different cement grinding circuit were completed In the first study, a circuit including open circuit HPGR, ball mill and air separator was sampled and chosen as the basic ...

HPGR test results published by Grier (1992) on gold ores from the Mt. Todd project showed significant energy savings for a HPGR/Ball Mill circuit as compared to a SAG/Ball Mill plant. By adding a Polycom high-pressure grinding roll, the throughput of existing plants can be increased by as much as 150% while simultaneously reducing the power ...
