A Review of the Modeling of High Pressure Grinding Rolls

It should be noted that grinding in roll crushers is completely different from HPGR grinding. In roll crushers, the gap is fixed and no compressive pressure is applied to the rolls. Hence, breakage occurs through contact with the rolls. Individual particles larger than the gap repeatedly break into smaller sizes until they pass through the rolls.
