Hydrocyclones can be used to separate suspended solids from liquids. In CE 225, the suspension is prepared in a tank. A pump delivers the suspension to the tangential inlet of the cyclone. A descending primary vortex is created in the cyclone. The downward taper causes the vortex to invert. In the middle it moves as a secondary vortex backward towards the dip tube, where the suspension emerges from the cyclone, having lost the coarse material in it. An air core forms inside the cyclone. Centrifugal forces cause the coarser solid particles in the primary vortex to become enriched. They are discharged with the bottom flow at the apex nozzle. It is mainly the fine material that is discharged from the top.
