The overall efficiency predicted by the CCD process is incorrect because of the inaccurate fractional efficiency curve generated by the CCD process (Kaspar et al. 1993). In order to use the CCD process, it is assumed that the design engineer will have knowledge of (1) flow conditions, (2) particulate matter (PM) concentrations and particle size ...

HYDROCYCLONES. The hydrocyclone is a simple piece of equipment that uses fluid pressure to generate centrifugal force and a flow pattern which can separate particles or droplets from a liquid medium. These particles or droplets must have a sufficiently different density relative to the medium in order to achieve separation.

Description. Hydrocyclone Separators are effective in removing suspended particles from any flow stream of water where the specific gravity (density) of the particle(s) is heavier than the water it is in; the more significant the difference in the gravity between the water and the particle, the greater the efficiency of the removal process.
The VorSpin Hydrocyclone features three improvements in hydrocyclone efficiency: A volute feed inlet; A fluted Vortex Finder; A non-plugging discharge Apex; The Volute feed inlet prevents the slurry from circulating back into the path of the incoming slurry, causing undesirable turbulence that reduces separation efficiency.

A hydrocyclone can handle very high slurry throughput rates, and often an entire battery of hydrocyclones can be found at a mineral processing facility. The advantage of fast processing by a hydrocyclone is somewhat offset by the associated high impingement wear rate of the hydrocyclone internal surface lining by the fast-moving abrasive slurries.
Hydrocyclone use is regarded as a method for separating and recovering chemicals from process residues by which the unreacted components can be recycled efficiently. However, hydrocyclones designed by conventional procedures may have some limitations regarding classification sharpness.
Hydrocyclones are very widely used for high-throughput coarse/fine particle separation in the mineral processing industry using a vortex effect, or simply slurry dewatering. They don't suffer from the rate-limiting steps of the alternatives: • Sedimentation settling: rate-limiting step is the sedimentation rate.
The gravimetric method was used to measure the separation efficiency of the hydrocyclone separators and compare the weights of the sludge discharged from the underflow and overflow outlets. The outlet flow ratio was optimized by adjusting the diameters of the spigot and vortex finder of the separators, which influenced the outlet flow rate.

Hydrocyclones are of cyclonic separators that separating product phases mainly on basis of differences in gravity with aqueous solutions as the primary feed fluid. As opposed to dry or dust cyclones, which separate solids from gasses, hydrocyclones separate solids or different phase fluids from the bulk fluid. A hydrocyclone comprises a ...

O) for low-efficiency units (high throughput), 1 to 1.5 kPa (4 to 6 in. H 2 O) for medium-efficiency units (conventional), and 2 to 2.5 kPa (8 to 10 in. H 2 O) for high-efficiency units (AWMA, 1992). When high-efficiency (which requires small cyclone diameter) and large throughput are both desired, a number of cyclones can be operated in parallel.
Reduced efficiency at less-than-capacity flow. Difficult to obtain good separation of substances of similar densities. Cannot handle viscous flow. Extremely high velocities cause abrasive wear. Hydrocyclones cannot produce completely dry underflow. Clogging of the dust outlet is common in reverse flow cyclones
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.. First …
Hydrocyclone Working Principle. The centre of this spiral is called the VORTEX. The purpose of the apex is to cause internal pressure for the cyclone and to create a vortex that extends all of the way to the top of the cyclone. In all hydrocyclones there are two outlets, one for the coarse material, this is the APEX, and the other for the fine ...
