Abstract
Après broyage dans un moulin 1 les déchets sont amenés pneumatiquement dans un cyclone 3 d'où ils tombent dans un réservoir de stockage 6 disposé au-dessus d'une trémie d'alimentation 4 d'une vis-bouchon 12 alimentant une extrudeuse 13. Le réservoir de stockage 6 et la trémie 4 comportent l'un et l'autre des arbres agitateurs 14, 15, 16, 18, 19, 20 munis de doigts agitateurs 17 et 21. A la sortie de l'extrudeuse 13, on obtient un bain qui peut être réincorporé dans un processus de fabrication.
