Copper removal from rejected pvc wire.

rejected pvc wire are a significant component of electronic waste, primarily consisting of a copper core and PVC insulation. Due to the high value of copper, recycling offers significant economic and environmental benefits. However, traditional incineration or landfilling not only wastes resources but also releases toxic gases. Therefore, developing efficient and environmentally friendly copper recycling technologies is crucial.

Copper recycling equipment primarily consists of a shredder, a sorter (such as an electrostatic separator or airflow separator), a copper shredder, and a dust removal system. The shredder pulverizes the wires into fine particles. The sorter separates copper and PVC based on their density or conductivity differences. The copper shredder further refines the copper particles, and the dust removal system ensures that the process meets environmental standards.

Equipment Workflow
① Shredding: Scrap wires are initially shredded by a shredder;
② Sorting: Copper particles and PVC are separated using a vibrating screen or airflow separator;
③ Purification: The copper shredder removes residual impurities, resulting in high-purity copper particles;
④ Dust Removal: Dust collection devices are installed throughout the process to prevent microplastic contamination.

After processing, copper recovery rates can reach over 98%, with purity exceeding 99%, allowing direct use in metallurgy or cable manufacturing. PVC plastic can be pelletized for reuse or pyrolyzed for energy conversion. The entire process is pollution-free, achieving resource recycling and green treatment.

This technology effectively solves the problem of discarded wire disposal, offering both economic and environmental benefits, and providing a viable solution for electronic waste recycling.
