In general, cyclones use centrifugal force to separate particles in a gas or liquid stream. In hydrocyclones, liquid is the fluid medium. There are two design classifications for cyclones. Uniflow or swirl tube cyclones are designed so that the clean gas or liquid leaves the cyclone in the same direction that the inlet gas flows.

Cyclones - Resource Book

In a cyclone, a higher feed density is analogous to a higher density (= more particles) in the glass of slurry. Particles will find it harder to sink so that only the large, heavy particles will make it to the wall. On the other hand, a lower feed density will allow the smaller, lighter particles to sink, reducing the cut point.

Separation of polymer particles using a hydrocyclone

separation efficiency of yeast was increased at higher pressures, lower inflow density of particles, higher temperature, and smaller diameter ofthe vortex finder. The importance ofthis experiment was that it presented the possibility that microorganisms can be separated using a small diameter hydrocyclone.

Hydrocyclones also find application in the separation of liquids of different densities. A different description: A hydrocyclone is a mechanical device designed to reduce or increase the concentration of a dispersed phase, solid, liquid or gas of different density, by means of centripetal forces or centrifugal forces within a vortex.

HYDROCYCLONES - airliquidsystems

Particles within the solution are accelerated outward toward the walls of the cyclone body by centrifugal force. This force is greatest on the particles of greatest mass (i.e. greatest size or relative density). As a result, the coarser, heavier solids migrate toward and along the inner wall of the cyclone leaving with some liquid as the underflow.

Hydrocyclones CONTROL DRILLING SOLIDS

Hydrocyclones separate solids according to mass, which is a function of both density and particle size. However, in unweighted drilling fluids, the solids density has a comparatively narrow range, and size has the greatest influence on their settling.
