Abstract

L'invention concerne l'industrie des matières plastiques. Elle a pour objet un dispositif d'alimentation pour une extrudeuse destinée à des matières thermoplastiques comportant un broyeur de pellicules de matières plastiques, un silo à rognures de pellicules disposé en aval du broyeur et un précompresseur monté à l'entrée de l'extrudeuse, la trémie d'admission du précompresseur pouvant être alimentée en rognures de pellicules à partir du silo, qui comporte un dispositi de mélange à recyclage 13 qui prélève les rognures de pellicules dans le bas du silo et les ramène dans le haut du silo. Ce dispositif est préféré pour alimenter les extrudeuses à pellicule.
