Abstract

La présente invention concerne un procédé de traitement de matériaux granulaires. L'appareil d'attrition pour réduire en poudre un matériau granulaire aggloméré comprenant une chambre 11 pour recevoir les morceaux de matériau aggloméré avec en-dessous un dispositif de criblage 19, il comporte des chambres d'évacuation du matériau 16 disposés de part et d'autre des moyens 15 pour mettre en vibration l'appareil, moyens qui ont une action dirigée sensiblement selon un cercle. Le procédé permet de réduire en poudre le sable de fonderie en vue de son recyclage.
