HPGR High Pressure Grinding Rolls Weir
Used in mining applications for the last 30 years, high pressure grinding rolls (HPGR) reduce 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 volume, exceeding its The highpressure roll grinding implements a material layer crushing, which is the mutual crushing between materials with very high crushing efficiency Generally, the energy consumption of highpressure roller grinding is greatly reduced compared to impact or sheartype crushing equipment(HPGR) high pressure grinding rolls/rollers for cement The technology's working principle is that two counterrotating grinding rolls expose a column of material to high pressure, which is distributed across the gap between the rolls Interparticle comminution is the HPGR specific grinding process in which material particles are crushed and ground within the compressed material bed and not by High Pressure Grinding Rolls (HPGR) TAKRAF GmbH
