Abstract
A method and an arrangement are provided for breaking up composite material comprised of elastic materials combined with metallic materials. The composite material is placed into an insulated vat holding liquid nitrogen via a transporting device and is positioned below a unipolar electrode arrangement. An energy source generates high-energy pulses that are applied to the composite material by the electrode arrangement. The composite material is torn apart by the high-energy pulses and is separated by a subsequently resulting pressure pulse.
Claims7
A method for breaking up composite material composed of elastic materials combined with metallic materials, including the steps of:
- placing the composite material into a vat with liquid nitrogen, with the use of a transporting device, for making the composite material brittle;
- generating high-energy pulses, with 200 to 1200J per pulse, from an energy source;
- applying, with an electrode arrangement, the high-energy pulses to the brittle composite material in the vat to tear the brittle composite material apart;
- and
- separating the metallic material from the elastic material by pressure pulses that result from the high-energy pulses.
An arrangement for breaking up composite material composed of elastic materials combined with metallic materials, including:
- a vat for holding liquid nitrogen;
- a transporting device for carrying the composite material into the vat with the liquid nitrogen therein;
- an electrode arrangement mounted in the vat so as to be positioned above the composite material transported into the vat;
- and
- a high-energy source coupled to the electrode arrangement for generating high-energy pulses, with 200 to 1200 J per pulse, that are applied to the composite material by the electrode arrangement for breaking up the composite material in the vat.
