hpgr roll crushing experience

Sep 05 2019 · One thing to note when deploying a HPGR in a pebble crushing circuit is that truncated feed one with a narrow size distribution may cause higher wear on the surface of the machine’s rollers than encountered in other applications as the more “mobile” particles generate a weaker autogenous wear layer where the coarse pebble fragments chip away at the coating on the rollsurface
