Abstract

A rotor for a sorting apparatus for cleaning fibrous suspensions such as produced from the making of paper is described. The rotor is equipped with sorter blades which extend substantially parallel to the axis of rotation and are set at a desired angle relative to the direction of rotation of the rotor so as to create a hydrofoil effect. The sorter blades are mounted to one or more supporting walls shaped in a spiral form to provide spiral surfaces which are coaxial with the axis of rotation of the rotor and impart a conveying motion to the fibrous suspension. Upon rotation of the rotor in a fibrous suspension entanglements by impurities are avoided and the danger of the occurrence of a blockage of the strainer used in the sorter apparatus is reduced.
