What factors affect the recycling rate of waste wires?

In the scrap metal recycling industry, purity equals profit. When you're considering investing in a cable granulator, the recycling rate is the most important metric. For professional-grade copper wire granulators, a reasonable and competitive copper recycling rate should be between 98% and 99.9%.

SUNYGROUP has nearly 20 years of experience in the waste wire recycling industry. We possess mature experience and equipment. So, what factors affect the recycling rate of waste wires? Here are some possible reasons for fluctuations in recycling rates:

1. Type of Waste Wire

Standard Industrial Cables: Easy to handle; recycling rate is typically close to 99.9%.

Hair-thin Wires (Automotive Wiring Harnesses): Because these wires are very light, they often "float" in the water along with plastic during air separation.

Professional Tip: To maintain a high recycling rate for thin wires, your machine must be equipped with an electrostatic separator to capture tiny copper particles that air separators cannot catch.

2. Blade Sharpness and Screen Size

If the blades are dull, they will "tear" rather than "cut" the wires, resulting in irregular shapes that are difficult to separate. Proper maintenance ensures that the material is crushed into uniform particles, which is crucial for the effective operation of a gravity separator.

3. Precision of Airflow Regulation

The air separator is the heart of the recycling process. A machine capable of precise frequency control (via a frequency converter) allows the operator to find the "optimal balance"—blowing away plastic while retaining even the finest copper particles.
