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.Process for recovering paper and crusher using this process. All the components of a paper mixture are simultaneously subjected to a grinding operation. Forces which are chosen to ensure progressive fragmentation of the components of said paper are exerted on the mixture. The pieces of paper are collected at different times. A crusher implementing this process comprises a rotor 2 and a grid or screen 14 around the rotor 2. The fins 18 rub the paper against the screen 14. Application: recovery of waste paper.
