  • Sorters is the one for the passage of the pulp particle suspension provided screen basket facing surface of the wings curved in the manner that the radial distance between the functionally effective wing surface and the facing Siebkorbction in the leading part of the wing first up to reduced to a minimum. After a short, about constant Minimum distance to the facing Siebkorb realization increases the radial distance to back end or the end edge of the wing back to.
  • sorters two basic types of sorters exist, namely on the one hand sorter with a from inside with Sorting material suspension feedable screen basket and inside the screen basket lying wings, so “centrifugal sorter”, and on the other hand sorter with rotating outside of the screen basket and the same at a small distance outside swept wings, with these so-called “centripetal sorters” the sorted material is supplied to the screen basket from the outside and the discharge of the purified pulp suspension is made from the inside.
  • the present invention is based on the observation that the hitherto customary design of the screen basket-near surface of the wings in the form of a Wing area, especially in the leading area of the wing provided distance reduction between the sash and strainer, neither off From a fluidic and energetic point of view, the effectiveness of the Separation process, throughput and separation efficiency is optimal.

Corresponding features are given in claims 6 and 7, which can achieve favorable flow conditions and separation results. In the case of a stepped configuration of the contour, the steps or points need not be arranged along a straight line, but may have a concave or convex overall course.
  • the contour of the wing widening from the front side to the rear, may again have angles running towards each other in its rear third.
  • the described contour shapes of the wings also contribute to the reduction of the flow resistance as it moves through the fiber suspension.
  • the suction effect can still be increased if - as provided for in accordance with claim 6 - it is ensured that the Wing surfaces extending transversely to the direction of rotor rotation, such as strip-like Have surveys, behind each one compared to the usual Suction effect of the wing surface locally enhanced suction effect occurs.
  • the nature of the arrangement of the individual wings on the rotor can be far in Borders vary, however, are in several rows one above the other and heights and / or circumferentially offset arranged wings particularly preferred.
  • the rotor itself may be formed in one piece. It may be expedient to use an embodiment in which a plurality of individual rotor modules are assembled to form a rotor of any desired axial extent, as specified in claim 10.
