Feb 01, 2006 1.. IntroductionSch nert (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) (Sch nert and Knobloch, 1984).The first commercial application of HPGR was in 1985 and its success
