摘要： A screening device for fiber suspensions, comprising a casing (1) with a screen means (5) and a rotor (6) with pulsation wings (9) located at the screen means (5), whereby a screening zone (7) is formed along the screen means (5). An inlet (2, 8) is provided for the fiber suspension, inject, to one end of the screening zone (7). A reject outlet (4) is provided from the other end of the screening zone (7). An accept chamber with outlet (3) for screened pulp (5) is provided in connection to the screen means (5). Means for the supply of dillution liquid to the screening zone (7) comprise at least one stationary nozzle (10, 12) located at the reject outlet (4) and directed into the screening zone (7) along the surface of the rotor (6).
