Abstract

A hydrocyclone has a separating part A with a diameter which toward its outlet end for the heavier fraction decreases gradually from a diameter 2 Ra, with the radius being subject to the formula: R=Rax 2ROOT 1-x/1. This describes essentially the shape of a parabola, so that the separating part can practically be considered as a paraboloid. Achieved thereby is an optimum separating performance of the hydrocyclone.
