ることになる。Known decanter-type centrifuges of the above type with surface portions νiii
41, the screw threads of the conveying screws in the face part and the bowl part are fixedly provided on the screw carrier. In the case of conveying screws designed in this way, it is possible to fit the gap between the outer edge of the screw thread and the inner wall of the drum or (rt) sieve wall exactly into the respective required gap during manufacture. For the above reasons, it is impossible. Even if this type of conveying screw of a centrifugal separator is machined and machined with great precision, the tolerance between the outer edge of the screw thread and the inside of the drum, ( In fact, a large deviation from the required gap width between the outer edge of the zero screw thread and the drum and wall, especially in the face area of a decanter-type screw centrifuge, can cause solids to accumulate. This will have a disadvantageous effect on dehydration.

常に好都合である。This object is largely achieved in that the solids removal screw in the surface part is arranged to be axially movable relative to the conveying screw in the bowl part. By moving the solid discharge screw installed in the sieve direction in the axial direction relative to the conveying screw in the bowl section, the gap width between the outer edge of the screw thread and the inner wall of the face section can be adjusted starting from the minimum gap. This is very convenient because it can be optimally adjusted to the desired value at any given time.

に有利である。In a further embodiment of the invention, at least one spacer is provided between the hollow body of the solids removal screw and the screw carrier of the conveying screw. By means of this spacer, the solids evacuation screw of the face part can be adjusted by a predetermined amount with respect to the conveying screw of the bowl part, thereby precisely adjusting the respective required clearance width between the screw thread free edge and the face wall. It is very advantageous because it can be maintained at the same time.
