Hydrocyclone Working Principle. The centre of this spiral is called the VORTEX. The purpose of the apex is to cause internal pressure for the cyclone and to create a vortex that extends all of the way to the top of the cyclone. In all hydrocyclones there are two outlets, one for the coarse material, this is the APEX, and the other for the fine ...

PRESSURE DROP The cyclone pressure drop is a function of the cyclone separator dimensions and its operating parameters. The pressure drop over a cyclone is caused by the change in the area, wall friction, change of the flow direction and the dissipation in the vortex finder (outlet tube). In general, the term 'pressure drop' means
