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 of the 2000s.
