ABSTRACT:
A method and apparatus for screening pulp, or like suspensions, having a consistency of about 6-15 percent. The pulp is passed into a chamber having a flat plate screen, and the pulp is fluidized by rotation of a disk, with vanes, mounted adjacent the screen. The disk may be constructed to allow circulation of rejects within the chamber. The chamber may be in communication with a second chamber having a similar screen and disk arrangement, with the rejects outlet from the second chamber in communication with the suspension inlet to the first chamber.
