  • Will HPGR replace SAG Mill and Vertimill displace Ball

    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.

  • How HPGR compares to conventional milling

    Aug 19 2019 · Traditionally the generated pebbles are re-crushed via cone crushers however the hard and abrasive nature of these pebbles result into significant liner wear and frequent cone crusher downtime. Integrating a HPGR into the pebble re-grinding circuit can alleviate the wear component and provide an improved overall feed to the (S)AG mill.
