Abstract
Procédé de récupération de papier et broyeur mettant en oeuvre ce procédé. On soumet simultanément tous les composants d'un mélange de papier à une opération de broyage. On exerce sur le mélange des forces qui sont choisies pour assurer une fragmentation progressive des composants dudit papier. Les fragments de papier sont récupérés en des temps différents. Un broyeur mettant en oeuvre ce procédé comporte un rotor 2 et une grille ou crible 14 autour du rotor 2. Des ailettes 18 frottent le papier contre le crible 14. Application : récupération de vieux papiers.
