Industrial Copper Wire Granulator for Waste Cable Recycling

The 1,000 kg/h industrial-grade copper wire recycling production line is a complete set of equipment designed for the shredding of waste cables, the separation of copper from plastic, and metal recovery. Through multi-stage shredding and two parallel sorting lines, it enhances processing efficiency and recovers fine copper particles encased within rubber and plastic insulation layers.

Multi-stage Shredding Equipment: Gradually Reducing Cable Size

This industrial-grade copper wire granulation production line utilises a multi-stage shredding system comprising twin-shaft shredders, single-shaft shredders and wire shredders. Each piece of equipment performs a specific processing task, gradually reducing the size of the waste cables from large dimensions to particles suitable for sorting.

The twin-shaft shredder is responsible for the initial shredding of mixed, bulky or bundled waste cables, reducing feed size and improving conditions for subsequent conveying. The single-shaft shredder further refines the material, making it easier for the cables to enter the fine-crushing stage. Subsequently, the cable pelletiser subjects the material to high-speed shearing and crushing, ensuring thorough separation of the copper conductors from the insulation.

The key to this staged crushing process lies not merely in increasing the crushing speed, but in controlling the particle size to create the conditions necessary for subsequent copper-plastic separation. For waste cables of varying diameters, structures and insulation materials, the actual equipment configuration must be determined based on feed size, copper content and target output.

Dual-line sorting system: Recovery of fine copper particles

After processing by the granulator, the material enters two parallel sorting lines. Each sorting line is equipped with an air classifier and an electrostatic separator, forming a continuous copper-plastic separation process.

The air classifier utilises the differences in density and air resistance between copper particles and rubber or plastic insulation materials to perform a preliminary separation of the shredded material. Lighter insulating materials and heavier metal particles follow different trajectories under the influence of the air flow, thereby achieving preliminary screening.

The electrostatic separator performs further separation of the fine copper particles and non-metallic materials remaining after air classification. By exploiting differences in the electrical conductivity of the materials, it improves the recovery efficiency of fine copper particles from rubber and plastic. The two parallel sorting lines share the material processing workload, making them suitable for continuous industrial production.

1,000 kg/h Throughput Capacity and Equipment Configuration

This production line is designed with a processing capacity of 1,000 kg/h and is suitable for waste cable recycling projects of a certain scale. It should be noted that 1,000 kg/h typically refers to the designed processing capacity of the entire line and does not equate to a yield of 1,000 kg of pure copper per hour. The actual amount of copper recovered also depends on the copper content in the waste cables, feed stability, shredding particle size and sorting efficiency.

The main equipment in the complete line includes a twin-shaft shredder, a single-shaft shredder, a cable pelletiser, two sets of air classifiers, two sets of electrostatic separators, and the corresponding conveying and control systems. When selecting equipment, particular attention should be paid to the maximum feed size, suitable cable types, installed power, purity of copper-plastic separation, and actual operating output.

For industrial-scale copper wire recycling projects, the combination of multi-stage shredding and parallel sorting strikes a balance between throughput and the recovery of fine copper. Contact SUNY GROUP for details on equipment specifications, process configurations and project solutions.
