Abstract

By a method and a plant according to the invention for the specific-gravity screening, especially of stone materials (12), the material (12) is dosed to the sieve (1) in such a manner that the heavy fraction (14) removed constitutes a predetermined part of the supplied material (12), and with an overflow plate (4) which separates the light fraction (13) together with the flushing water, and with a bulkhead (5) for the determination of the level of the water (15) in the vessel (6), specific-gravity screening can be carried out with a hitherto-unknown high degree of precision, and this is achieved even though the differences in the grain size and/or the specific gravity of the component parts are minimal. Aggregate material can hereby be screened for concrete mixtures which are completely free of the quality-decreasing types of flint which are of lower specific gravity than the preferred types of stone, and which can thus be screened out by means of the plant. <IMAGE>
