<p>The apparatus consists of a cylindrical metal container (1) on the inside of which are arranged, in order, from top to bottom: - a chamber (C) for the continuous loading of the material, already rough-sorted for bulky items, to be treated; - an assemblage of rotating plates (DR,DF) fitted with blades (2) and knives (4) respectively for the bursting of sacks containing the material and the breaking-up of the material itself; - a plurality of chambers (C1,C2,C3) and of rotating plates (D1,D2,D3) for the sequential specific selection of components of the waste on the basis of volume and specific weight. For this purpose, the selection plates have a central part (9) with calibrated perforations, of decreasing dimensions from top to bottom, while the container (1) has side openings (U1,U2,U3) for the ejection on the outside of the components selected; - a receiving chamber (CF) for the residual component and a rotating blind plate (DC) for the ejection on the outside of this component through a side opening UF in the container. The plates can be driven peripherally or centrally. In the first case, each plate is rotated by its own electric motor (M1,M2,M3,MF) so that the speed and the direction of rotation of a plate are independent of those of the other plates. Advantages: the apparatus is capable of carrying out, continuously, a complete process of primary selection. With peripheral motorization (independent), there is the possibility of adapting the operation of the apparatus to different situations. The invention is illustrated in Figure 2.</p> |
