At present, the new copper wire machine produced by KLAY can realize the directly crushing and sorting of waste wires containing plugs. The iron and brass pieces in the wire plugs can be separated without affecting the purity of the copper and plastic granules. When using wire granulation machine to process the waste plug wires directly , it is necessary to equip some corresponding additional device to separate the iron and brass pieces in the wire plug, for example, magnetic iron removal, vibrating separating table. By this way, the blades in wire crusher recycling machine line can be protected well.
