How to get out the copper wire in the scrap wire

Waste wire and cable treatment methods

1, manual stripping method: pure manual stripping, because of the efficiency is not high, the cost is large, the operating environment is relatively poor and other reasons, this method has been eliminated by the vast majority of enterprises.

2, incineration method: the plastic skin of the wire and cable with fire, burn off the outer skin recovery core. This method will produce a large number of toxic gases, serious pollution of the environment; oxidation of the core in the combustion process will also reduce the recovery rate of metal.

3, mechanical stripping method: the use of mechanical equipment for wire and cable processing. For coarse diameter cables generally use wire stripping machine, less than 20mm of wire using copper rice machine processing. This method is currently more mainstream processing methods.

4, chemical method: the use of chemical principles, the decomposition of wire and cable processing, but the decomposition of liquid will produce new pollution. According to current environmental requirements, do not recommend this treatment method.

5, freezing method: the use of liquid nitrogen as a freezing agent. Wire and cable will become brittle in the low temperature environment, after crushing and vibration. Can make the wire skin and core separation. This method is more environmentally friendly, but the cost is too high.
