Oct 02 2019 · HPGRs compress and grind the particle bed in the operating gap between two counterrotating rolls The equipment provides a high capacity low energy alternative for applications with conventional tertiary and quaternary crushing and grinding with size reduction reaching from 100 mm feed down to 25 microns product
Thanks to the ability to handle a continuous stream of material HPGRs are considered to be energy efficient grinding machines in general Metsos HRC equipment goes a bit further They direct the feed material straight to the crushing zone and adjust the speed and pressure in order to avoid wasting energy
The authors commented that the HPGR in quaternary mode is a powerful tool for capacity increase and that efficient classification is the key for further energy savings However tertiary plus quaternary HPGR use is less efficient than fine screening at the tertiary stage while the limits on fine wet screening have yet to be determined
Case Study of Dry HPGR Grinding and Classification in Ore Apart from tertiary and quaternary crushing applications in a wide variety of ore types High Pressure Grinding Roll “HPGR” technology is also applied in regrinding of iron ore pellet feed Hpgr Crusher Iron
many applications Tertiary and quaternary crushing stages can be replaced by a single large capacity unit operation also having the ability to takeover part of the ball mill grinding task Requiring less process stages an HPGR significantly reduces overall circuit energy consumption grinding media consumption and wear cost The Enduron
HPGRs can be employed in brownfield projects to debottleneck conventional crushingmilling circuits so as to increase total plant capacity Furthermore they can also be used as tertiary andor quaternary crushing stages or in the pebblecrushing stage to improve downstream milling performance
