  • the plate package has a "distributor shaped "holder 10, which has an inner cylindrical portion 10a and an axially adjoining conical section 10b. Between the conical portion 10b and the drum lid 7 are the actual arranged conical plate 11, which preferably by means of spacers are spaced, which are adapted to the particular application (molded Moldings, punctiform spacers, etc.).
  • the disc package 9 may be formed be that the supply of the centrifugal material to be clarified takes place radially from the outside (not shown here).
  • the derivation of the clear phase is carried out by a manifold 14 at the inner Diameter of the plate 11 in the wall of the cylindrical portion 10b.
  • the manifold 14 is preferably at least partially on a smaller Diameter than the outer wall of the screw body 3, which is a more energy-efficient Operating conditionally as arranging the manifold on a larger Diameter, which is also theoretically conceivable.
  • the manifold 14 finds an axial continuation in a bore 15 of the drum cover, which in a radially outwardly extending drain 16 for the clear phase opens.
  • the concentrate room is located outside on the Tellerpakt 9, the diameter of the drum shell 1 is executed continuously and no extension includes.

  • the diameter of the drum shell 1 is this area formed substantially constant.
  • Applicant's Varipond system can be used (regulating disc 22, which is axially slidable before expiry DE 43 20 265). Also other settings of the mirror as a disc package downstream peeling disc imaginable.
  • bracket 10 and / or on the drum cover 7 are also in an advantageous Way at the side facing away from the plates 9 side of the introduction of the centrifuged material formed in the plate package supporting ribs 23.
  • the centrifugal material 21 passing through the centrifugal material flows at the ribs 23 in the Rising channels 13 of the plate package 9, where the clear phase to the manifold and the Solids are discharged to the outside.
  • the solids are from the Räumansatz 17 taken and promoted by the screw to the conical section 5b.
