Abstract: The invention relates to a sorting element for a sorting device. The sorting element comprises a substrate from which a multitude of fingers project. The fingers are arranged on the substrate along a first helical line.

Abstract: A screen device for sorting screening material into one or more fine grain fractions and one or more oversize grain fractions. The screen device includes a frame and a roller screen including screen rollers which are arranged, such that they can be rotary-driven about a roller axis each, next to each other and which are supported on the frame and which each comprise a roller body and one or more screen structures which protrude radially relative to the roller body. There is a fine grain screen gap between the roller bodies of respectively adjacent screen rollers, through which a fine grain fraction falls, while an oversize grain fraction is conveyed on the roller screen in the axial direction of the rollers when the screen rollers are rotary-driven.

Abstract: A sorting device that can be transported by road or rail has rotary driven sorting rollers, supported on a frame, that together form a roller screen for sorting a material mixture into a fine grain size which falls through the roller screen and an oversize grain that is conveyed by the sorting rollers over a side edge of the roller screen. An oversize grain conveyor and collector is arranged below the sorting rollers. A channelling means extends along the side edge and is inclined in an operating position towards the oversize grain conveyor and collector, at least in sections, between an upper region, which faces the side edge at a distance, and a lower region which is near the oversize grain conveyor and collector, in order to channel oversize grain, which is conveyed over the side edge of the roller screen, downwards to the oversize grain conveyor and collector.

Abstract: The invention relates to a screen element (1) for a disc screen device which has a plurality of rotable shafts (2, 3) oriented parallel to one another, on each of which a plurality of screen elements (1) that are spaced axially from one another are non-rotationally arranged, wherein the screen element (1) has elastically flexible fingers (4). The screen element is implemented such that at least one of the fingers is designed as a cleaning finger (5) free of reinforcement for cleaning in particular the collar (6) of a screen element (1) arranged on the neighboring axis of rotation (2, 3).
