1.Core Working Principle of Copper Granulator
The working principle of the modern dry-type copper granulator is based on mechanical crushing + specific gravity wind sorting + vibration screening technology. The whole process is pure physical separation, no chemical pollution, and no copper oxidation.
The principle can be divided into four core stages:
Step 1: Mechanical Crushing
The high-speed rotating cutter head crushes waste wires and cables into small mixed particles of copper and plastic. The crushing gap is precisely adjusted to ensure that the copper core and plastic skin are completely dissociated without adhesion.
Step 2: Vibration Screening
The vibrating screen screens out oversized materials and unseparated mixed particles, returning unqualified materials to the crushing chamber for secondary processing to improve separation completeness.
Step 3:Specific Gravity Wind Separation
Using the density difference between copper and plastic, strong adjustable wind power separates heavy copper particles and light plastic particles. Copper sinks and plastic floats, realizing precise separation.
Step 4: Fine Dust Collection
The equipped dust removal system collects fine powder and tiny impurities to ensure clean finished copper granules and meet environmental protection emission standards.
2.Complete Processing Flow of Copper Granulator Production Line
A standard copper granulator production line follows a fixed closed-loop processing flow, which is suitable for small, medium and large recycling factories. The standardized process greatly improves finished product purity and yield.

4.Why Copper Granulator Has Higher Recovery Rate
Many small recycling workshops still use manual peeling or simple wire stripping machines to process messy wires, resulting in extremely high copper loss. The copper granulator solves the industry pain points fundamentally.
1. Suitable for all messy and fine wires Wire stripping machines cannot process ultra-fine wires and tangled harnesses, while copper granulators have zero requirements for wire neatness.
2. Zero copper powder loss Precision crushing and closed-loop sorting system avoids fine copper loss, and the material utilization rate is close to 100%.
3. No residual plastic adhesion Complete dissociation ensures pure copper output, effectively increasing the resale price of recycled copper.
5.Frequently Asked Questions About Copper Granulator Working Principle
Q1: Will the copper granulator damage copper materials? No. The physical crushing and wind sorting process will not cause copper oxidation or chemical damage, and the copper granules maintain high purity and toughness.
Q2: Can one machine process all kinds of wires? Yes. It can process household miscellaneous wires, industrial cables, automobile harnesses, computer wires, communication wires, and mixed waste wires.
Q3: Is dry-type copper granulator environmentally friendly? Absolutely. No open fire, no waste water, no exhaust gas, fully meets EU, Southeast Asia, Africa and global environmental protection standards.
6. Conclusion
The copper granulator relies on mature physical crushing and gravity separation principles to achieve high-efficiency and high-purity waste wire recycling. Compared with traditional processing methods, it has irreplaceable advantages in recovery rate, purity, environmental protection and profit. For modern standardized recycling plants, a dry-type copper granulator is essential core equipment for processing messy mixed wires.
