High pressure grinding rolls are an energy efficient grinding solution, and now has improved this technology even further. The HRC™, our innovative approach to HPGR technology, is like no other HPGR on the market.
iron ore pellet feed grinding. High Pressure Grinding proven technology High Pressure grinding has become the "go to" technology for size reduction in mineral applications with more than 200 High Pressure Grinding Roll (HPGR) installations across the world. Most new greenfield projects include HPGRs as part of their
Thus, some of the finish grinding work is handled by the highpressure grinding roll. The throughput of the existing grinding system can be increased by 50 to 70%, while power consumption can be cut by 20 to 30%. Additional options for highpressure grinding roll use in gold ore comminution circuits are illustrated in Figure 11.
Currently, there is no standard recognized benchscale laboratory test for sizing or modelling a high pressure grinding roll (HPGR) in hard rock mining. As a result, metallurgical studies are prohibitively expensive and not economical for earlystage projects.
One advantage of this test is the generation of a seasoned charge. This has particular value when considering autogenous circuits where the larger lumps must be present in the mill to provide grinding media. Additional Equipment Available for Grind Testing • Polysius Labwal High Pressure Grinding Rolls • High Pressure Gravity Roll variability
"The increasing adoption of HPGR in the mining and cement industry is expected to propel the market growth" The global High Pressure Grinding Roller (HPGR) market is anticipated to witness a robust growth owing to the increase in the adoption of the mining and cement industry.
