Abstract: Process as described in which the extraneous matter is in particular pollutants such as PCB, oil and similar, as well as useful materials such as coal and the like. The bulk material concerned is mixed with washing compounds such as water, tensides and the like and mechanically agitated. The process in accordance with the invention is characterized in that the mixture of bulk material and washing compound is exposed to powerful agitation, whereby the extraneous matter is separated under the effect of high-energy impacts, and that the bulk material, extraneous matter and washing compounds are then separated. Furthermore, the bulk material thus treated can be subjected to further washing with water in order to remove any remaining extraneous matter. The apparatus for performing the process is based on essentially vertical impact walls, in the form of turns of an endless screw (2), arranged inside a tubular container (1) with an essentially horizontal axis (8), said screw being rotated by means of a rotary drive (3) and linear drive (4) and simultaneously displaced with a back and forth jolting movement in order to separate in this way the extraneous matter from the bulk material by the action of high-energy impacts.

Abstract: Dans le procédé décrit, les corps étrangers sont notamment des polluants, tels que le PCB, le pétrole et similaires, ainsi que des substances utiles telles que le charbon et similaires. Le produit en vrac concerné est mélangé avec des agents de lavage tels que de l'eau, des tensio-actifs et similaires, puis agités mécaniquement. Le procédé décrit est caractérisé en ce que le mélange de produits en vrac et d'agents de lavage est soumis à une agitation puissante, provoquant la séparation des corps étrangers sous l'effet de chocs de haute énergie, et en ce que le produit en vrac, les corps étrangers et les gaents de lavage sont ensuite séparés. De plus, le produit en vrac ainsi traité peut subir un nouveau lavage à l'eau, afin d'éliminer les corps étrangers restant éventuellement. L'appareil permettant la mise en oeuvre du procédé se fonde sur des surfaces de choc essentiellement verticales, sous la forme des spires d'une vis sans fin (2), agencées à l'intérieur d'un récipient tubulaire (1), avec un axe (8) sensiblement horizontal, ladite vis étant entraînée en rotation au moyen d'un entraînement rotatif (3) et d'un entraînement linéaire (4), et simultanément déplacée par à-coups avec un mouvement de va-et-vient afin de séparer ainsi les corps étrangers du produit en vrac sous l'effet de chocs de haute énergie.
