The comminution of rock and ore materials consumes ~1.5-1.8 % of the total energy production in mining intensive countries (Tromans, 2008). Several research findings show that there are ways of utilizing compressive breakage modes that are more energy efficient compared to conventional grinding circuits based on large inefficient tumbling mills. …

These roll crushers have large forces of compression and are called high pressure grinding rolls (HPGR). The present trend is to replace secondary cone crushers by HPGR. The work at Polysius [3] and described by Friedrich and Baum [4], and Otte [5] indicates considerable metallurgical advantage in the extraction of minerals such as gold …

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. …
