Abstract
A continuously operating centrifugal separator suitable for concentration of suspended solids contained in a liquid feed material, having a drum for separation of the feed material into a concentrated fraction and a clear fraction, a paring chamber 15 for discharge of the concentrated fraction, a first passageway 13 for delivery of the concentrated fraction from the periphery 12 of the drum to the paring chamber, and a second passageway for receiving concentrated fraction from the paring chamber and discharge thereof from the drum. The invention provides a conduit means for recycling some of the concentrated fraction which has been conveyed to the paring chamber to the first passageway. Thereby the concentration of solids in the concentrated fraction can be controlled without interferring with the separation being effected in the drum.
