How does a Flottweg C-series Decanter work? The concept corresponds to the fundamental function of a decanter centrifuge. The Flottweg C-series accelerates the supplied separation medium particularly effectively, thus saving energy. The solids are thrown onto the inner wall of the bowl by acceleration and discharged via the decanter scroll to the conical bowl end. In contrast to other decanter centrifuges, the C-series decanter have a double cone and a baffle plate.
