High pressure grinding rolls (HPGR) appliions in the 1.. IntroductionSchönert (1979) has shown that the most energy efficient method of comminuting particles is to compress them between the two plates. Compressing a particle bed between two counter rotating rolls was achieved by the invention of the high pressure grinding rolls (HPGR) (Schönert and Knobloch, 1984).The first commercial appliion of HPGR was in 1985 and its success resulted inHigh Pressure Grinding Roller (HPGR) FL Dorr HPGR High Pressure Grinding Roll for the minerals industry Global Installations • Canada • Saudi Arabia • Turkey 2 • United Kingdom HPGR equipment is a
