The cement roller press has a high energy utilization rate and remarkable energy-saving effect in the material grinding process. In cement plant, cement roller press is a kind of
Read More2006-2-1 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 application of HPGR was in 1985 and its success
Read MoreAs new-type and energy-efficient cement grinding machine, cement roller press has advantages of energy-saving, high efficiency, less steel consumption and less noise. Both apply for new cement plant building and old cement plant revamping. According to the data, roller press helps ball mill system to increase the output by 30-50%.
Read MoreThe roller press is often used where energy-efficient grinding of large product quantities is required. The two rollers, rotating in opposite directions, exert very high pressure on the material, effectively crushing and weakening the particles (microscopic cracks), so that the subsequent fine grinding is easier.

Read MoreThe HPGR (high pressure grinding rolls/rollers) is the core equipment of the high pressure grinding process. The machine reduces particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them. This forces the rocks against each other and compresses the feed’s density to 80% of its solid []
