ENDURON High Pressure Grinding Rolls The Group. ENDURON® High Pressure Grinding Rolls ENDURON® High Pressure Grinding Rolls High Pressure Grinding Rolls (HPGR) consist of two rolls of identical dimension, that rotate against each other at the same circumferential speed. The main grinding action is a result of interparticle crushing.
Used in mining applications for the last 30 years, High Pressure Grinding Rolls (HPGR) reduce particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them.
It has the same working principle as Raymond Mill, but its grinding device is fixed with 1000 - 1500 kg pressure springs. When the machine works, the grinding roller, under the action of high pressure spring and centrifugal force, rolls close up to grinding ring, its rolling pressure is 1.2 times higher than that of Raymond mill given an identical condition and its output may increase 20% to ...
