  • Hydrocyclone Working Principle

    ClassificationPurposeMechanismOperationEffectsExampleSignificanceThe third type of classification used in mining is the Hydrocyclone, commonly called a Cyclone. Unlike the others it has no moving parts and is worked in conjunction of another piece of equipment, a pump. To understand the Hydrocyclone Working Principle we must first know its components. Beginning at the top, there is the OVERFLOW DISCHARGE.Read More
  • Hydrocyclone Feed Pump amp; 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. There is a cycle to a surging pump box that causes this pressure fluctuation.

  • CAVEX Hydrocyclones Cortech Engineering California

    When only water is fed into the hydrocyclone, a negative pressure is created at the bottom as a result of the siphon from the extended overflow pipe. Once you introduce solids, the discharge regulator opens up after a sufficient pressure is achieved. Excess water is removed and the underflow density is maximized.

  • The Effect of Inlet Velocity on the Separation Performance

    Near the center of the hydrocyclone, the axial velocity is positive and the fluid flows upward to the overflow. This region is referred to as the inner vortex region. In the central region of the hydrocyclone, the axial velocity is negative. This is because the pressure in the central region is lower than the external atmospheric pressure.
