A pressure screen for screening pulp, the pressure screen comprising a housing (1) and a rotor (3) rotatably mounted within the housing, at least two axially successive screen cylinders (7a to 7c), mounted coaxially with the rotor, and foil blades (11a to 11c) coupled to the rotor. The pressure screen comprises a ring-shaped conduit (12a, 12b) between the successive screen cylinders (7a, 7b; 7b, 7c), said conduit allowing dilution water to be introduced into the pulp flowing from one screen cylinder to another. |
