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.

Grinding is a subprocess of finely grinding ore in advance, such that the ground output can be physically separated into iron ore and impurities in the downstream subprocess. In many cases, an autogenous mill (AG mill) or a semiautogenous mill (SAG mill) is used for the primary grinding, and a ball mill is used as the secondary for further
