Multi-stage method of separation for sorting and processing inhomogeneous rubble and plant for carrying out the method.

摘要

With this method and the device for carrying it out, the sorting of inhomogeneous building rubble is to be improved so that a highly selective separation of the rubble fractions is made possible. For this purpose, building rubble supplied in rubble containers (2) is tipped onto a vibro channel (3) and under the influence of the vibrations produced by the vibro channel (3) is loosened and conveyed to a preseparator (4) with conical screening strips which separate bulky refuse components from the rest of the building rubble. A conveyor belt (13) conveys the building rubble not separated out by the preseparator (4) to the input of a finger screen (12). Between the preseparator (4) and finger screen (12) a magnetic separator (15) is arranged. The finger screen (12) provided with a finger cover (12.4) separates from the rest of the building rubble a fine fraction (C) which for economic reasons is not divided up any further and is taken to tips. The building rubble conveyed to the input of the air separator (14) is divided up in a preseparator section (16) into two fractions which are each conveyed via air streams with the purpose of separating off a light fraction (E) with combustible components from a heavy fraction (D).
