hpgr vs high pressure roller mill

hpgr vs high pressure roller mill

After the introduction of high compression grinding mills (High pressure grinding rolls (HPGR), vertical roller mill (VRM) and Horomill), various circuit configurations have been developed for energy efficient grinding. In this study, in order to evaluate and compare the performances of these cement grinding technologies, industrial scale data were collected from HPGR-ball mill, VRM, Horomill and multi-chamber ball mill …

    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 …
