An apparatus for sorting fiber suspensions comprising a stationary cylindrical screen cage and a rotor having a cylindrical wall mounted concentrically relative to the screen cage to form an annular space, the unsorted fiber suspension entering the annular space at one end and flowing generally toward the other end of the annular space, the fiber suspension increasing in consistency as it flows toward the other end of the annular space, the rotor having openings and/or elevations to cause the dilution of at least a portion of the thickened stock in the annular space not passing through the screen with a portion of lower consistency fibrous suspension to allow it to flow more readily. In one embodiment the rotor is mounted within the screen cage and a portion of the unsorted fiber suspension is introduced to the interior of the rotor, passing outwardly through openings in the rotor along the length of the annular space to dilute the thickened, dewatered suspension within the annular space.
