How Cable Granulators Separate Copper from PVC

Copper Cable Granulator Systems work by first shredding cables into uniform pieces. A magnetic separator removes ferrous contaminants, and a granulator then crushes the material to separate copper conductors from the plastic insulation. After granulation, air separators use density differences to separate light plastic from heavy copper granules. Linear vibrating screens classify particles by size for optimal separation. Electrostatic separators can be added to achieve higher copper purity, resulting in clean copper granules and plastic.

Throughout the crushing and separation process, pulse-jet dust collection systems are installed to capture airborne dust and maintain a clean working environment. This design allows the entire line to comply with stringent environmental and occupational safety standards in the United States, the European Union, and other international markets. The final copper product, commonly referred to as “copper rice,” is bright, clean, and ready for direct sale to smelters or copper product manufacturers, while the separated plastic is suitable for secondary recycling.
