A Review of the Modeling of High Pressure Grinding Rolls
The roll crusher model was previously developed by Austin et al. (1980). 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. The resultant particle size distribution is not only a function of the feed particle

Jun 15 2019 · Next the two-toothed roll crusher was optimized based on the framework proposed by the Whiten model. The reasonable rolls gap and teeth length should be 75 mm and 23 mm respectively. Further a physical model of a two-toothed roll crusher was established to obtain the optimized roll diameter it was later found to be >660 mm.
