  A Review of the Modeling of High Pressure Grinding Rolls

  Other designations were also used for the high pressure grinding technology with respect to a wide range of applications from coarse crushing to very fine grinding, such as ‘high pressure roller crusher’, HPRC. The generic term that has been widely settled upon is HPGR, high pressure grinding rolls, and is used in this paper as well.
