Abstract
A presser belt separator for separating a mixture of flowable and non-flowable constituents has a pressure belt that is driven downstream to engage part of a circumferential surface of a perforated drum. A belt pressing structure and a presser roller presses the belt against the surface of the drum to form a draw-in wedge for drawing in the material to be processed between the presser belt and the perforated drum. The belt presser has a surface contour that engages the belt to form a curvature in the central area of the presser belt. The surface contour decreases in curvature from an upstream region of the belt presser to a downstream region thereof. The presser structure is also resiliently urged against the perforated drum by force-adjustable pressure springs.
