PROCEDURE AND INSTALLATION FOR PROCESSING COMPOSITE MATERIALS Russian patent published in 2011 - IPC C22B7/00 C22B21/00 F27B1/00 

FIELD: machine building.

SUBSTANCE: procedure consists in stages of supply of certain amount of composite material containing polymer and aluminium in first reactor, in heating composite material in non-oxidising medium at temperature sufficient for polymer volatilisation and production of hydrocarbon side product and aluminium in first reactor, in supply of aluminium free form one polymer into second reactor and in heating aluminium in non-oxidising medium at temperature sufficient for aluminium melting in second reactor. The installation consists of not less, than two reactors, one of which is equipped with an external heating element set around a cavity for mixing wherein there are arranged at least two screws each including a shaft and at least two internal heating elements positioned on it. The second reactor is equipped with a system of plasma heating located near a melting bath covered with material possessing fire-proof properties. The reactor has a case set around the cavity for mixing composite material, the plasma heating system arranged on the case and connected with the cavity, an inlet orifice for reception of certain amount of aluminium, free of polymer, an outlet orifice for discharge of melted aluminium communicated with the cavity, and heat insulating material applied in the said case at amount sufficient for maintenance of working temperature in the melting bath.

EFFECT: processing composite materials including paper-plastic, aluminium and materials consisting of thin-sheet plastic-aluminium used for manufacture of packages for food products and industrial products with facilitation of re-use.
