Should a cyclone separator be able to be used for the concentration of liquid phases?

The one used in liquid phases is called a hydrocyclone; it is generally used for solid-liquid separation. Whether you want to purify a liquid or concentrate a solid, it’s up to you to decide: lol. A difference of more than 3 times in density between solid and liquid is generally required to be effective. Cyclone separators are used for gas-solid separation. The solid outlets of both the hydrocyclone and the cyclone are located in the middle at the bottom: victory:

Depending on the medium used, they can be called by different names; their outlets are only located at the bottom

Thank you all; it’s helped me learn a lot again.

Lz said that this type of separator should be a “cyclone”. A cyclone is a common separation and classification device, and its working principle relies on centrifugal sedimentation. When the two (or three) phases of the mixture to be separated enter the cyclone tangentially from its periphery at a certain pressure, intense three-dimensional elliptical, highly rotating shear turbulent flow is generated. Due to the difference in particle size (or density) between the coarse particles (or heavy phase) and the fine particles (or light phase), the forces acting on them such as centrifugal force, centripetal buoyancy, and fluid drag vary. As a result of centrifugal sedimentation, most of the coarse particles (or heavy phase) are discharged through the bottom outlet of the cyclone, while most of the fine particles (or light phase) are discharged through the overflow pipe, thereby achieving the purpose of separation and classification. 　　The hydrocyclone consists of a hollow cylinder at the upper part, and an inverted cone that is connected to the cylinder at the lower part; these two components together form the working cylinder of the hydrocyclone. Depending on different requirements, hydrocyclones can also be equipped with feed pipes, overflow pipes, overflow ducts, and sand discharge ports.
