Abstract

L'invention concerne un dispositif et un procédé permettant de séparer les copeaux d'aluminium des copeaux de fonte grise issus d'un mélange de copeaux. A cet effet, les copeaux sont recueillis et cédés à une première voie de transport (20). Ils sont transportés le long de cette première voie de transport (20) où ils sont soumis à un champ magnétique de telle façon que les copeaux d'aluminium quittent par gravité cette première voie de transport (20) au niveau d'un premier emplacement (34) et que les copeaux de fonte grise maintenus par la force d'attraction magnétique du champ magnétique poursuivent un parcours prédéterminé sur cette première voie de transport (20) jusqu'à un deuxième emplacement (36) où ils quittent également cette voie de transport (20). Les copeaux sont recueillis séparément respectivement au premier et au deuxième emplacement (34, 36).
