Abstract

Apparatus for the screening of fiber suspensions is disclosed including a housing, a reject outlet and an accept outlet, a screen located within the housing, a rotor including pulsation wings mounted therein, a reject chamber in the housing for collecting a reject portion of the fiber suspension, and an accept chamber for collecting the accept portion of the fiber suspension passing through the screen and supplying it to the accept outlet, each of the pulsation wings including an outside face and an inside face, a leading edge, a trailing edge, and upper and lower ends so that a predetermined pressure difference is created between the outside and inside faces of the pulsation wings in the direction of the lower edge thereof.
