Abstract

An apparatus for the centrifugal separation of a solid-liquid mixture including an elongate centrifuge drum rotatable about a central axis, a coaxially located conveyor worm within the drum having worm helix flights on a worm drum therein, an opening for the discharge of a light fraction and an opening for the discharge of a heavy fraction, the opening for the discharge of the light fraction located in a radius from the drum axis less than the radius of the worm drum and the opening for the heavy fraction being located at a radius relative to the axis of the drum less than the radius of the worm drum.
