A closer look at increasing HPGR efficiency through

Feb 01, 2021Edge effect is a condition widely observed in High Pressure Grinding Roll (HPGR) operations that gives rise to reduced comminution at the edges of the roll surfaces. This effect is caused by a reduction in the local crushing pressure at the edges of the rolls resulting from the sliding friction between the static cheek plates and HPGR feed material. Practically, this has an impact on equipment

HPGR

HPGR is popular in many field, especially in comminution of metal ore with good production indexes. By the way, HPGR also can be used in pre-treatment of raw materials of pelletization and sintering. Therefore it is hard to estimate the cost, unless you do enough experiments to be clear about the characteristics of the porphyry copper ore.
