Abstract (en)
[origin: CA2021478A1] The hydrocyclone has a separating part A with a diameter which toward its outlet end for the heavier fraction decreases gradually from a diameter R? with the radius being subject to the formula This describes essentially the shape of a parabola, so that the separating part can practically be considered as a paraboloid. Achieved thereby is an improved separating performance of the hydrocyclone.
