ABSTRACT:
In an apparatus for dividing a suspension of fibrous cellulose pulp into a plurality of portions in a closed housing having multiple inlets and outlets, the present invention suggests that the closed housing is divided into two chambers, each provided with at least one inlet and at least one outlet, and that in the first chamber a separating device is arranged, rotating at high speed, to separate undesired parts from the suspension via an outlet, the inlet of the second chamber comprising an opening arranged between the first chamber and the second chamber to transfer the suspension which has been substantially freed from undesired parts. Furthermore in the second chamber a rotor provided with blades is arranged, the rotor being connected to the separating device in the first chamber, the separating device and rotor being driven by a common shaft, and a screening device cooperating with the rotor, to divide the suspension into different fractions which leave the second chamber by individual outlets.
