Abstract
An apparatus for the separation of solids and liquids from a suspension has a hollow drum rotatably mounted about a horizontal axis. The drum wall is a screen made of a plurality of wires, preferably wedge-sectioned wires; spaced apart in a parallel arrangement and lying axially along the drum. Inlet means direct the suspension against the inner surface of the wall at an angle less than right angles, and preferably substantially tangentially to the inner surface, in a direction opposing the rotation of the drum. The separated solids remain within the drum and are extracted therefrom by suitable means.
