About Gomine Copper Wire Granulator
A gomine copper wire granulator is an industrial machine designed to separate copper from plastic insulation in scrap electrical wires. It uses mechanical processes—including shredding, grinding, and air separation—to recover high-purity metal while minimizing waste. These systems are widely used in metal recycling facilities, e-waste processing plants, and cable dismantling operations.
The core function revolves around size reduction: insulated wires are fed into the machine where they’re crushed between rotating knives and fixed blades. The resulting mixture of fine metal particles and plastic fragments then passes through an air classifier that separates materials by density. Final outputs include clean copper granules (typically 95–99% purity) and plastic residue suitable for secondary recycling or disposal.
Manufactured by Shanghai Gomine Machinery Co., Ltd., these machines are engineered for continuous operation, often integrated into automated recycling lines. They support various input diameters—from thin communication cables to thick power cords—and can process anywhere from 100 kg/h up to several tons per hour depending on model and configuration.
Why Gomine Copper Wire Granulator Is Gaining Popularity
As global demand for recycled metals rises, so does the need for efficient recovery technologies. One major driver behind the growing adoption of the gomine copper wire granulator is its ability to extract valuable raw materials without using chemicals or water, making it both environmentally friendly and cost-effective.
Urban mining—the practice of reclaiming metals from electronic waste—has become increasingly viable due to rising copper prices and stricter environmental regulations. According to industry estimates, over 50 million metric tons of e-waste are generated globally each year, much of which contains recoverable copper 2. Machines like those from Gomine allow recyclers to tap into this resource efficiently.
Additionally, their relatively low operating costs compared to smelting or chemical stripping methods make them attractive for small and mid-sized enterprises. With automation features such as automatic feeding and dust collection becoming standard, labor requirements have decreased significantly, further boosting ROI.
