Abstract

L'invention concerne un procédé et un appareil de tri de copeaux (3). Les copeaux, qui ont une énergie cinétique, sont séparés les uns des autres en fonction de leur forme ou de la longueur de leur courbe de vol qui dépend de leur résistance à l'air. L'énergie cinétique des copeaux est générée par un dispositif d'éjection mécanique (6) éjectant les copeaux, au moyen d'un convoyeur annulaire ou au moyen des ailes d'un déchiqueteur soufflant.
