Baffles are added to the blade members of the rotor of an apparatus for screening fibrous stock to cause the flow of stock within the screening zone along the length of the blades to angle away from the blades rather than parallel with the blades. Passageways are added to allow untreated stock to be added at points deep within the screening zone to maintain a proper water to fiber ratio throughout the screening zone.
