<p>Process and device for the separation of reusable metal constituents from a composite material, especially a laminated plastic-metal. The invention is characterized by a device for carrying out this process according to any one of claims 1 to 3. The device is characterized by having a heat treatment enclosure supplied with composite material scraps which are subjected therein to pyrolysis at a temperature of 350° to 450° and preferably approximately 400°, the combustion gases of the binders in the compound material being evacuated from the enclosure for treatment and purification by conventional means. The device is also characterized by having means for crushing material from the heat treatment enclosure, means for separating the reusable metal constituents from the by-products, and means for packaging the metal constituents so separated.</p> |
