Dec 21, 2018· Since the dried material in the grinding gap is largely subjected to interparticle high-pressure grinding, the roll bodies of the polycom® achieve a much longer service life than the grinding elements of conventional grinding systems, espe - cially at high specific wear rates.
The grinding elements are two counter-rotating rolls, between which the material is crushed. One roll is designed as a fixed roll and the other one as a floating roll. The required comminution pressure is transmitted via the floating roll. The high-pressure interparticle comminu-tion produces compacted cakes of material
