Core Processes of Waste Wire Recycling Equipment

SUNYGROUP’s waste wire recycling equipment utilizes dry physical crushing and separation technology. The entire process requires neither water washing nor chemical reagents, relying solely on physical mechanical action. The core processes are as follows:

Step 1: Crushing

Waste wires enter a heavy-duty crusher where high-wear-resistant blades (such as SKD-11 steel) shear them at high speed, reducing the wires into a mixture of copper and plastic granules sized 2–5mm.

Step 2: Airflow Separation

This step exploits the difference in specific gravity between copper (heavy) and plastic (light). A blower directs air from the bottom; combined with the vibration of the separation bed, this causes the lightweight plastic insulation to "float" upward and be discharged, while the heavier copper granules settle toward the opposite end.

Step 3: High-Voltage Electrostatic Separation

This stage targets automotive "flying wires," capillary-thin filaments, and brush-like wires—materials where copper strands are so fine that traditional airflow separation often fails to achieve clean separation. The electrostatic separator utilizes a high-voltage electric field to extract 100% of the micron-level copper particles mixed within the plastic.

The core value of the dry copper recycling machine lies in its "closed-loop, water-free, and zero-emission" nature. It eliminates the drawbacks of traditional wet-washing methods, which generate highly toxic wastewater, instead achieving efficient separation entirely through mechanical forces and electrical properties. This enables recyclers to rapidly secure facility approvals from local environmental agencies (such as the EPA or the European Environment Agency) and bring compliant projects online in the shortest possible time.
