  • Hydrocyclone Feed Pump Pressure PSI vs Operating Parameters

    For a hydrocyclone to work at peak efficiency the volume of slurry and the feed pump delivery pressure must remain constant. If the cyclone feed pump is allowed to SURGE, the up and down pressure will cause poor separation at the point of high and low operating pressure.

  • How energy efficient is HPGR? SAIMM

    54% of the energy reduction (2 038 kJ/lb Cu) is related to wear steel energy equivalent (SAG mill liners and ball consumption) and the remaining 1 705 kJ/lb Cu is lower electric power consumption (lower efficiency of size reduction in the SAG mill versus HPGR).
