Hydrocyclones are used in desliming, degritting, concentration, recovery of solids, clarification, open-circuit classification, and closed-circuit grinding. The hydrocyclone below is used to remove polypropylene powder from a solvent recovery unit. Cyclones can recover powder coatings, dust, chemicals, and catalysts.

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.
Hydrocyclones are widely used in petrochemical industry to separate particles from fracturing flow-back fluids, mineral processing and other fields, because of the advantages of easy operation, simple design and low maintenance cost [1, 2].Separation efficiency, cut size and pressure drop are significant indicators for measuring the …

1. Pressure at the inlet of the Hydrocyclone can tell you a lot. Pressure at the inlet of the Hydrocyclone is an important indicator of where the separation point (also called cut point or d50) will be. The separation point is the size at which a particle has a 50-50 chance of reporting either to the underflow or overflow.
Hydrocyclones with a flat-bottom structure reduces the misplaced fine particles due to the effect of the internal swirling flow and the axial circulation flow in the spigot. The MS type has the lowest imperfection value and the cut size of 76.5 μm implying a sharpness separation sharpness and an appropriate separation result.
