Replacing traditional primary grinding equipment with high-pressure grinding rolls (HPGR) consists of another energy-saving approach (Napier-Munn, 2015). Therefore, improving the process control of an HPGR circuit may enable further reductions, but studying this solution requires simulation models.

High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating.

The High Pressure Grinding Rolls comprises a pair of counter-rotating rolls mounted in a sturdy frame (Fig. 1). ... In the machine the feed material is compressed between two counter-rotating rolls, in which one of the rollers rotates on a fixed axis while the other is allowed to move horizontally. The moveable roll is forced up against the ...
