The highpressure grinding rolls (HPGR) technology is increasingly being considered for hard ore comminution due to its significant benefits in energy consumption compared to conventional semiautogenous grinding (SAG) mill circuits. It has been shown that HPGR circuits can reduce the energy requirements by 10 to 40% [1,2,3,4].

Two main types are indicated. The first type where the rolls are rotated in opposite direction with one roll spring loaded. Here, the mineral particles are nipped and crushed as they pass between rolls. In the second type, known as high pressure grinding roll (HPGR), the mineral sizes are reduced by compressive and interparticle pressure.
