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 R.sub.a, with the radius being subject to the formula: EQU R=R.sub.a .multidot..sqroot.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.
