ABSTRACT:
A sorter for paper pulp suspension including a rotationally symmetrical wire cage and a rotor supporting a plurality of vanes for rotating about the interior of the cage for moving suspension through the wire cage, the vanes being non-uniformly spaced. An annular pulp chamber surrounds the screen for collecting the pulp. A suspension outlet at the bottom of the pulp chamber receives the pulp from the pulp chamber. The pulp chamber extends axially beyond the lower end of the wire cage. An annular damping chamber surrounds the lower end of the pulp chamber and flow from the pulp chamber to the pulp outlet is past the damping chamber. The damping chamber develops a pool of the suspension in it. A pressurized gas cushion above the pool of suspension in the damping chamber controls the level thereof and damps the motion of the pulp in the pulp chamber.
