Abstract
Provided is a manufacturing method and a device for recycled molding material of aluminum foil composite films that can collect and efficiently recycle no longer used aluminum foil composite films and that also greatly contribute to CO2 emission reduction. The manufacturing method and device for recycled molding material of aluminum foil composite films, in which the mesh dimensions of a pulverizer screen mesh member for aluminum foil composite films are made larger than the mesh dimensions of a kneading extruder screen mesh member of a kneading extruder for gelling the pulverized aluminum foil composite film.

1-18. (canceled)
A method of producing recycled molding material from an aluminum foil composite film obtained by adhering an extrusion molding film to the surface of an aluminum foil via an adhesive layer, comprising
- a crushing step for crushing the aluminum foil composite film by fixed blades and cemented carbide blades mounted on a rotor,
- a crushing screen mesh member passing step for passing the crushed aluminum foil composite film through a crushing screen mesh member, while the extrusion molding film is maintained in an adhered state to the surface of the aluminum foil via the adhesive layer,
- a kneading extrusion step for gelatinizing the crushed aluminum foil composite film by applying heat and pressure, while the extrusion molding film is maintained in an adhered state to the surface of the aluminum foil via the adhesive layer, and
- a kneading extrusion screen mesh passing step for passing the gelatinized aluminum foil composite film through a kneading extrusion screen mesh member comprising a kneading extrusion screen mesh member having an opening dimension smaller than the opening dimension of the crushing screen mesh member.
An apparatus for producing molding material recycled from an aluminum foil composite film obtained by adhering an extrusion molding film to the surface of an aluminum foil via an adhesive layer, comprising
- crushing means for crushing the aluminum foil composite film by fixed blades and cemented carbide blades mounted on a rotor,
- crushing mesh means for passing through the crushed aluminum foil composite film, while the extrusion molding film is maintained in an adhered state to the surface of the aluminum foil via the adhesive layer,
- kneading extrusion means for gelatinizing the crushed aluminum foil composite film by applying heat and pressure, while the extrusion molding film is maintained in an adhered state to the surface of the aluminum foil via the adhesive layer, and
- kneading extrusion screen mesh means for passing the crushed aluminum foil composite film through a kneading extrusion screen mesh means having an opening dimension smaller than the opening dimension of the crushing screen mesh means.
