Hydrocyclone - Wikipedia

A hydrocyclone (often referred to by the shortened form hydroclone or cyclone) is a device to classify, separate or sort particles in a liquid suspension based on the ratio of their centripetal force to fluid resistance. This ratio is high for dense (where separation by density is required) and coarse (where separation by size is required) particles, and low for light and fine particles. Hydrocyclones also find application in the separation of liquids of different densities.

Hydrocyclones - an overview ScienceDirect Topics

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.

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.

A hydrocyclone with a volume of 2.56 cm 3 was studied as a potential cell retention device for mammalian cell cultures (6 L volume). For the feasible operation range (0.9 to 1.6 L/min flow corresponding to pressure drops of 0.4 to 1.3 bar) the hydrocyclone was characterized with regard to flow split (underflow‐to‐overflow ratio) and flow ratio (underflow to supply).
