The highpressure grinding roll (HPGR) is a type of roller mill that continuously produces particlebed comminution. The HPGR was introduced by Schönert and first installed in the cement industry in the 1980s (Schönert, 1988, Schönert, 1985). ... Wear due to compression and abrasion from particles is a critical issue for high pressure ...
