Abstract

A fully jacketed centrifuge with a helical conveyor for separating mixtures of solids and liquid has apertures below the surface of the liquid in the jacket of the drum. Some of the centrifuges solids are let off through the apertures. Inside the helical conveyor is, in addition to one inlet space for the mixture of solids and liquids, another inlet space that has an access and that communicates with channels that extend in the vicinity of the apertures into the vicinity of the jacket. The apertures are positioned in interchangeable mouthpieces. The concentration of solids flowing off out of the apertures is controlled by constantly returning part of the solids that emerge from the flowoff through the access, the second inlet space, and the channels into the vicinity of the apertures.
