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. Hence, breakage occurs through contact with the rolls.

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.

Proven technology for efficient grinding: High Pressure Grinding Rolls. Optimise your results with a high pressure grinding roll, the most energy-efficient way to process mining ores.

Optimise your results with a high pressure grinding roll, the most energy-efficient way to process mining ores. Suitable for industries including iron ore, precious metals, base metals and other, the HPGR's ability to weaken rock structure provides metallurgical benefits downstream (i.e. enhanced kinetics for heap leaching).

Figure 1 illustrates the principles of high pressure roll grinding and compares it to conventional comminution. Operating Experience With HPGR in the Minerals Industry. High-pressure grinding rolls were first applied in the minerals industry in 1985 in cement plants. The main objective for the use of HPGR was the significant energy savings ...
