ABSTRACT:
A suspension of fibrous cellulose pulp is separated into at least two portions in an apparatus comprising a closed housing having inlet and outlets, and a rotor means provided with projections, said rotor means comprising a first rotor part surrounded by a screening means, the first rotor part and the screening means in their axial extension forming a screening zone and being arranged to cooperate with each other during rotation of the first rotor part for screening the suspension in a fluidized state. The rotor means comprises a second rotor part located immediately adjacent to the first rotor part, a rigid, water-impervious wall member surrounding the second rotor part. The second rotor part and the wall member form in their axial extension a pre-treating zone located immediately upstream of the screening zone and cooperate with each other during rotation of the second rotor part, Futhermore, the second rotor part has projections which, during rotation of the rotor part, run along the inner cylindrical surface of the wall member, without coming into contact therewith, so that the suspension is pre-treated and converted into a fluidized state suitable for screening in the screening zone located immediately thereafter.
