Abstract

A screening device for fiber suspensions, comprising a casing (1) with a screen means (5) and a rotor (6), provided with pulsation wings (9), located at the screen means (5), whereby a screening zone (7) is formed along the screen means (5). The screening device is formed with an inlet (2, 8) for the fiber suspension, inject, at one end of the screening zone (7), a reject outlet (4) at the other end of the screening zone (7) and an accept chamber with outlet (3) for screened pulp. A stationary flow restriction (10) is located at the reject outlet (4) between the rotor (6) and the end of the pulsation wings (9) to counteract a flow past the end of the wings.
