摘要

In an apparatus for sorting building rubble in order to obtain building material, in particular concrete aggregate and components, such as wood, which are light with respect to the latter, in a dense-medium washing drum with water, which dense-medium washing drum comprises a drum which has a horizontal axis of rotation and has a plurality of transport screws fastened on the inside and having multiply interrupted screw surfaces, it is provided in accordance with Patent ... (P3713663.1) according to the invention that the interruptions (32) in the screw surfaces (27, 28) have diverging edges (30, 31) proceeding from the drum casing (26) to the inner edge of the screw plate, the screw plates (33), which are bounded by the interruptions (32), of every screw surface (27, 28) being arranged in the screw surface plane (Fig. 1).
