ABSTRACT:
In a refiner for treating cellulose pulp or similar material of the type comprising two intermeshing rotary screws operating in a housing having a material inlet and a material outlet, the surface of each screw comprises a feeding thread section merging into a feed-resisting surface section, the outlet being provided in a side-wall of the housing near the zone where the feeding thread sections on both screws end and the feed-reversing surface sections begin. The outlet opens into an outwardly flaring collar having a plane mouth opening oblique in relation to the direction of material discharge through the material outlet. The mouth opening cooperates with a closure element to restrict the outlet area to control working pressure conditions within the housing.
