ABSTRACT:
In an apparatus for dividing a suspension of fibrous cellulose pulp into a plurality of portions, a closed housing is provided which is divided into two chambers, each provided with at least one inlet and outlet, and in the first chamber a separating device is arranged, rotating at high speed, to separate undesired parts from the suspension via an outlet. An inlet to the second chamber is provided in the form of an opening between the first chamber and the second chamber for transferring the suspension which has been substantially freed from undesired parts. Furthermore, in the second chamber a cylindrical screening device is arranged, connected to the separating device in the first chamber, the separating device and screening device being driven by a common shaft. A support provided with blades cooperates with the screening means to divide the suspension into different fractions which leave the second chamber by individual outlets.
