Abstract
The invention resides in the provision of a sludge recirculation controlled in this manner within the centrifuge rotor itself. For this reason there has been arranged centrally in the rotor, apart from a previously known reception chamber (10) for separated sludge, a recirculation chamber (14) to which sludge is transferred from the reception chamber (10). An overflow outlet (15) maintains a free liquid surface in the recirculation chamber (14) at a predetermined radial level. Recirculation channels (16), which are formed so that the flow therethrough will automatically be controlled depending upon the viscosity of the separated sludge, will conduct such sludge from the recirculation chamber (14) back to the radially outermost parts of the separation chamber (5).
