Why skewing is not beneficial for your HPGR - Outotec

Jan 31, 2022In traditional, non-flanged HPGRs, the pressure across the rolls is uneven, caused by a phenomenon called "edge effect". This happens because ore bypasses the comminution process on both sides of the rolls. Static cheek plates are used to keep the material in between the rolls when it is being crushed and therefore to minimize the edge effect.
