Using Piston Press Tests for Determining Optimal Energy Input for an HPGR Operation
July 21, 2016 | HPGR Evaluation
Multiple trade-off studies have shown that grinding circuits with high pressure grinding rolls (HPGR) can be more energy efficient than the circuits with semi-autogenous (SAG) mills. However, such studies are difficult to conduct because the current practice of sizing and selecting the HPGR requires large samples for pilot-scale testing that are expensive and difficult to […]
