ABSTRACT:
An apparatus for screening a suspension of fibrous cellulose material containing undigested wood comprising a shaft rotating in a housing and an elongate screen disposed in a screening chamber. This screen comprises a stationary screening member and a rotating screening member connected to the shaft. Each of the screening members comprises a plurality of parallel rings disposed with predetermined axial distance from each other to form circumferential openings, the rings of the stationary screening member and the rotating screening member being arranged to partially close each other's openings between the rings to define circumferential screening gaps therebetween. According to the invention the stationary screening member is in the form of a unitary body rigidly connected to the housing so that at least circumferential movement is prevented. The rotating screening member is likewise in the form of a unitary body but it is connected to the shaft for common rotation therewith. The apparatus enables digested pulp to be screened without dilution.
