Comminution in HPGR is a result of high interparticle stresses generated when a bed of solids are compressed while moving down the gap between two pressurized rolls. The priority that HPGR can generate fine products followed by grinding in ball milling, puts a competitive pressure on the application in semiautogenous (SAG) mills.

The Coalition for Energy Efficient Comminution (CEEC) has been established and is supported by a broad range of mining sector companies keen to accelerate awareness, knowledge transfer and, by implication, improve energy and cost outcomes in the substantive area of comminution.
Far less studied is the effect of feed moisture. This paper investigates both the overall and the specific comminution efficiency of a circuit consisting of a pilot HPGR unit followed by a batch ball mill as a function of the moisture level in the HPGR feed. Forsterite olivine sand (−7 mm) supplied by Sibelco Nordic was used as feed material.
