ABSTRACT:
An apparatus for processing fiber suspensions containing usable fibers and suspended dirt particles to be separated from the usable fibers, the specific weight of the particles differing distinctly from that of the usable fibers, is described. The apparatus comprises a drum-shaped outer housing having (i) and inflow end accommodating a body rotationally symmetric to the housing axis and being provided with a tangential inlet pipe for the fiber suspension to be processed, and (ii) an outflow end being provided with an axial outlet pipe for a lightweight dirt component of the suspension and an outlet pipe for a usable component of the suspension. In order to also separate a heavy dirt component of the suspension, and to minimize cost due to wear, the housing and the outlet pipe for the usable component are stationary, the rotationally symmetrical body is a rotor rotationally drivable about the housing axis, and a separating wall rotationally symmetrical with the housing axis is provided for defining an outer annular chamber between the circumferential housing wall and the separating wall. The annular chamber is open at its one end facing the rotor and is provided at its other end with a radial outlet pipe for heavy dirt particles. The separating wall further circumscribes an inner annular chamber circumscribing the outlet pipe for the lightweight dirt component, and the outlet pipe for the usable component opens into the inner annular chamber.
