Feb 01, 2006 1.. IntroductionSchnert (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) (Schnert and Knobloch, 1984).The first commercial application of HPGR was in 1985 and its success Dec 21, 2018 A rolling success For decades, polycom high-pressure grinding rolls have been used successfully in the grinding of raw materials and binding agents. polycom HPGR grinding is based on the principle of supplying the material to be ground to two counter-rotating rolls
