The high-pressure grinding rolls (HPGR) technology is increasingly being considered for hard ore comminution due to its significant benefits in energy consumption compared to conventional semi-autogenous grinding (SAG) mill circuits. It has been shown that HPGR circuits can reduce the energy requirements by 10 to 40% [1,2,3,4].
Compared to the roller mill and multicracker system, the hammer mill requires more energy. For a similar grinding intensity (particle size reduction), the hammer mill consumes more specific mechanical energy (kJ/kg) compared to the roller mill (Wondra et al., 1993; Vukmirović et al., 2016; Thomas et al., 2018).
roller grinding mill A roller grinding mill is a machine used to grind solid materials into fine powders. It works by applying force to the material being ground between two or more rotating rollers.

Previously, roller mill technology could not achieve mean grain particle size below 600 µm on a consistent basis. Previous research often used a roller mill to grind coarse particle sizes due to the ability to achieve a precise target followed by grinding with a hammermill to grind to a finer particle size (Nemechek, 2016). However, recent ...
