1. The metal trap transports the pulverized waste through a pipeline, and uses a metal trap to separate metal scraps having a diameter of 0.75 to 1.2 MM during the transfer.

2. The electrostatic separator pulverizes the mixed material and puts it into an electrostatic separator. By using different charging characteristics of metal and plastic, metals such as copper and aluminum can be separated. This method is applicable to the treatment of metal-filled composite materials, cable materials and metal-plated plastics.
3. Dissolution Separation The metal parts coated with the plastic coating are immersed in a suspension containing methylene chloride, a nonionic surfactant, paraffin and water to dissolve and separate the plastic coating.
4. The embrittlement separation cools the mixed waste of metal and plastic to the embrittlement temperature of the plastic, and then pulverizes, and then separates the metal from the plastic by the wind screen separation method.
5. The stripping wire of the cable sheath, the sheath material of the cable mainly includes polyvinyl chloride, polyethylene (including cross-linked polyethylene), synthetic rubber and natural rubber. In addition to the above electrostatic separation method, there are two methods, dry method and warm method. The method can effectively separate plastic, rubber and copper, aluminum core wire.
(1) Dry separation: The inside of the cable is uniformly heated by a far-infrared device, and the outer skin is manually peeled off.
(2) Wet separation: The aluminum wire is immersed in a solution of a penetrating agent (surfactant), heated to 70-90 degrees, and then peeled off the skin, and then continuously washed with an organic solvent several times to completely remove the tar.
