Abstract

In a method of separating granular goods of different specific gravity, by separating the goods, by a forced air flow therethrough while the goods are on a goods support subjected to a vibration, into a layer of heavier fractions and a layer of lighter fractions, separating the layers and separately discharging the layers, the goods are pre-sorted, in advance of charging thereof onto the support, into a bottom layer, enriched with the heavy fractions, and a superposed layer, free of the heavy fractions. The two layers, while in such superposed relation, are then charged onto the goods support. The apparatus includes a goods feeding device, for pre-sorting of the goods, in the form of a vibrating duct having a gas permeable bottom wall. The duct forms an initial sedimentation path of the heavy fraction of the goods, and the discharge end of the duct is spaced from the outlet for the heavy fraction to form a succeeding sedimentation path of the heavy fraction charged onto the goods support.
