Abstract

L'invention concerne un dispositif (1) pour séparer un matériau de chargement, en particulier un matériau de chargement non homogène, doté d'au moins deux éléments de rotation (2) en particulier conçus sous forme d'arbres de vis sans fin, les éléments de rotation (2) étant reliés entre eux par l'intermédiaire d'au moins un moyen de liaison (3), en particulier conçu sous forme de chaîne à rouleaux, d'un système d'entraînement (4), de sorte qu'au moins deux éléments de rotation (2) directement adjacents soient accouplés dans le sens de rotation. Selon l'invention, au moins un élément de rotation (2) est associé à un système (5), en particulier destiné à déplacer l'élément de rotation (2), qui, à l'état relié par l'intermédiaire du moyen de liaison (3), permet le désaccouplement de l'accouplement dans le sens de rotation desdits éléments de rotation (2) directement adjacents.
