Abstract
A static screen separator compact in both a vertical and a horizontal sense, including an inclined screen structure and a facing feed or head box from which a liquid-solids mixture overflows onto the screen. The head box is located to the front or flow face of the screen and nests therewith, substantially within the vertical and horizontal limits thereof. The head box embodies means defining an overflow lip which guides the slurry form of the liquid-solids mixture onto the flow face of the screen structure, which lip is flexible as to its contour both in the sense of flow and in a sense transversely thereof. The arrangement assures a smooth transition of the slurry from the head box to the screen flow surface irrespective of the nature or character of the contained solids. The overflow lip is reversely bent at the discharge end thereof which is resiliently biased to assume a pre-set position to contain the flow to the screen structure as it is caused thereby to move down the screen flow face in a uniform sheet-like flow.
