This compilation of examples from the literature is therefore far from complete, but is encouraging nonetheless. HPGR machines have been installed for the treatment of
Where HPGR technology has replaced traditional methods of crushing and grinding such as SAG or ball mills, customers have seen energy savings of up to 40%, and substantially improved mineral liberation. Find out more about the Enduron HPGR:
Comminution. Comminution till is defined as a 'very dense till that appears to have been formed by abrasion of bedrock and the crushing of detritus dragged along underneath the ice, accompanied by a mixing process that results in the incorporation of rock powder produced by abrasion at the till–rock interface into the overlying glacial load' (Elson, 1988).

An HPGR cannot replace a SAG mill. Also required to get the feed into the HPGR is a secondary crusher(s) and perhaps a tertiary crusher(s). The HPGR is often a quaternary crushing device which is the reason that the footprint for an HPGR plant is so large. To place a ball mill or a VERTIMILL directly on the HPGR product may work on soft iron ...

The parameter M i takes on different values depending on the comminution machine: M ia for primary tumbling mills (AG/SAG mills) that applies above 750 μm; M ib for secondary tumbling mills (e.g., ball mills) that applies below 750 μm; M ic for conventional crushers; and M ih for HPGRs. The values for M ia, M ic, and M ih were developed using the SMC Test® combined …
The HPGR (high pressure grinding rolls/rollers) is the core equipment of the high pressure grinding process. The machine reduces particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them. This forces the rocks against each other and compresses the feed's density to 80% of its solid […]
