Abstract
A twin hydrocyclone used for instance in cellulose and paper mills for purifying pulp suspension, the twin hydrocyclone consisting of two hydrocyclones mounted with their larger ends against each other and having one common infeed connector and one common purified fraction discharge connector. The hydrocyclones of prior art have the drawback of complex design and of division of the feed flow causing disturbances in the feed flow in view of the hydrocyclone's operation. The twin hydrocyclone, meant to solve these problems, is characterized in that the feed flow from the common infeed connector of the hydrocyclones is directed to each hydrocyclone as a separate feed flow by means of a helical member the helices of which constitute, in each hydrocyclone, feeding ducts confined by the walls of the hydrocyclones.
