Abstract
In a sorting method for fiber suspensions, a dividing wall (3, 3') is used comprising openings via which the compenent particles in the suspension S to be sorted are classified according to their size. The beneficial transporting away of the rejected component particles is thus achieved on the inlet side (4) of the dividing wall (3,3') with the aid of flow blades (7,7'), whereas, on the outlet side (5), pressure pulses produced by clearers (6) act through the openings of the dividing wall preventing them from clogging up.
