The workflow adopts a multi process collaborative design: the waste cables are first crushed into segments of about 3 centimeters by a shredder, and then finely ground into particles through a two-stage shearing method. Subsequently, the magnetic separator removes iron impurities, and the mixed particles enter the air flow separator to complete preliminary separation using the difference in specific gravity between copper and plastic. The undifferentiated materials will be further purified by an electrostatic sorting machine, equipped with pulse dust removal equipment throughout the process to ensure no dust pollution.
The mainstream models in the market are divided into two categories: dry and wet. The dry type model adopts the air flow+electrostatic sorting process, which does not require water and has a sorting rate of over 99%. It also meets environmental standards and has become the mainstream in the market; The wet type machine model draws on the principle of mineral processing and uses a gravity shaker for sorting. Although it is suitable for a wide range of impurity lines, it has a small amount of water pollution problem.
The high-quality copper rice machine adopts PLC intelligent control and supports mixed processing of large and small cables. The purity of the separated copper rice is comparable to electrolytic copper and can be directly used. Plastic can also be recycled and reprocessed. This characteristic of “turning waste into treasure” makes it indispensable in the treatment of waste cables such as automobiles and communications, providing key support for efficient resource utilization and environmental protection.
