Typical energy savings of 10-20% can be expected when installing HPGR vs. a SAG mill. Wipf(2005) showed why conventional Bond Work index tests on HPGR product is likely to under-estimate the energy savings that can be achieved by installing HPGR. Energy efficiency of HPGR is, however, ore-specific.

• AG and SAG mills • Ball mills • Rod mills • Crushers • High Pressure Grinding Rolls (HPGR) POWER-BASED EQUATIONS General The approach divides comminution equipment into three categories: • Tumbling mills, eg AG, SAG, rod and ball mills • Conventional reciprocating crushers, eg jaw, gyratory and cone • HPGRs

Aug 19, 2019· HPGR wear vs conventional mills. Ball, SAG and rod mills all require their grinding media to be regularly replaced, unlike a HPGR. High Pressure Grinding Rolls have lower maintenance overheads than ball and rod mills, primarily because the grinding media in conventional mills needs to be replaced on a more regular basis.

HPGR and ball mill circuit. This is a highly experimental model. Use at your own risk! The high pressure grinding roll (HPGR) and ball mill circuit can be thought of as a variation on the classical single stage ball mill (SSBM) circuit with the final stage of cone crushing replaced by an HPGR.
