A time dynamic model of a high pressure grinding rolls crusher
The crusher was then retrofitted with hydraulic cylinders to increase the pressure between the rollers. This was the predecessor to the high-pressure grinding rolls (HPGR) crusher, which became popular in Europe for applications in the cement industry. The introduction of the HPGR in minerals processing sparked at the beginning Grinding between rotating rollers An Enduron® HPGR reduces particles by compressing and grinding the feed between two counter rotating, parallel rollers. This forces the rocks against each other and compresses the feed’s density to 85% of its solid volume. This compression is achieved by applying high pressure of up to nearly 300MpaEnduron High Pressure Grinding Rolls Weir Group
