    From the early 1960’s until the mid 1980’s, dense medium cyclone circuitry design technology did not change appreciably. The basic design, which was both highly flexible and highly efficient, was consistent with technology developed by the Dutch State Mines (“DSM”) in the mid 1940’s. During this period, the “typical” dense medium cyclone circuit was designed to process raw coal

  • Hydrocyclone Feed Pump & Pressure PSI vs Operating Parameters

    For a hydrocyclone to 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. There is a cycle to a surging pump box that causes this pressure fluctuation. First the pump pumps all of the slurry out of

These parameters are inlet velocity, pressure drop and collection efficiency of the cyclone. An accurate prediction of cyclone pressure drop is very important as it relates directly to operating costs. Variation
