Morrison Project - HPGR Trade-off Study 2.0 BACKGROUND HPGR have been in operation for some time and were originally developed and applied in the cement industry. The technology was introduced into the mining industry in the early 1980s, with the first HPGRs used for the crushing of kimberlite in diamond mines.

Robust HRC™ high pressure grinding rolls (HPGR) High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed ...

More recently a HPGR-HPGR dry-processing circuit has been chosen for the Iron Bridge Magnetite Project instead of the AG-ball mill alternative (Fortescue, 2019). Following an extensive on-site pilot program costing $500 million, Fortescue reported that the results indicated energy savings of over 30% ( Mining Technology, 2021 ).

The material is fed to the HPGR by gravity and dragged into a compression zone between the rolls. The nip angle (α) represents the point in which the roller force starts acting on the material, thus starting the packed bed compression.The nip angle is dependent on the roller diameter and several material properties such as particle size and shape, …
