A Review of the Modeling of High Pressure

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. Austin et al. (1993) defined two sets of selection functions based on the geometry of the gap in a HPGR. The first selection function was
