Are scrap automotive wires, tangled telecom cables, and discarded copper-aluminum radiators filling your scrap yard without generating expected profits?
Burning insulation is environmentally hazardous, prohibited by EPA regulations, and oxidizes copper into a lower grade. Manual wire stripping, on the other hand, is incapable of handling high volumes of fine, capillary cables below 2mm.
The Shuliy dry-type copper wire granulator offers an industrial-grade, eco-friendly solution. Integrating heavy-duty alloy shredding, precise Italian airflow suspension separation, and high-voltage electrostatic extraction, our advanced copper wire granulator transforms mixed scrap cables into pure, market-ready “copper rice” pellets and clean plastic flakes in a single automated pass.
With capacities spanning 100 kg/h to 1000 kg/h and recovery purity exceeding 99.9%, Shuliy machinery empowers scrap yards, metal processors, and e-waste recyclers worldwide to maximize profit margins while complying with strict local environmental standards.
What Materials Can the Shuliy Copper Wire Granulator Process?
A common question from metal recyclers is: “Can your machine handle my specific cable mix without clogging screens or melting plastic?”
Our copper wire granulator is engineered with an adaptable crushing chamber and customizable screen sieves (2mm to 6mm), making it compatible with over 95% of industrial and commercial scrap cable types:

Core Structural Innovations: Engineered for Zero Loss & Zero Pollution
Unlike generic wire choppers on the market that struggle with melted plastic, constant blade wear, and dust leakage, each Shuliy copper wire granulator is manufactured with specialized industrial features:
① Integrated Monobloc Structure (Plug & Play)
- Petite empreinte: The compact machine integrates feeding, crushing, dust extraction, and gravity separation onto a single reinforced base frame.
- Instant Commissioning: No civil foundation or complex anchoring is required. Place it on level ground, connect the 3-phase power supply, and begin processing immediately.
② Intelligent PLC Automation
- Equipped with a sealed, intuitive touch-screen PLC electrical cabinet.
- A single operator can monitor motor amperage, adjust feeding speeds, calibrate airflow volume, and handle vibration frequency.
- Automatic reverse-rotation protection prevents motor burnout if oversized scrap is introduced.
③ SKD-11 Alloy Blades with Water-Cooled Chamber
- High Wear Resistance: Knives are forged from premium Japanese SKD-11 alloy die steel, heat-treated to HRC 58–60 for prolonged sharpness and impact resistance.
- Splayed Alternate Shearing: Blades are configured in an alternating splayed layout, providing progressive scissor-like slicing rather than brute-force impact. This design cuts electrical power consumption by 20%.
- Circulating Water Cooling: Scrap wire processing generates friction heat that can cause soft PVC or rubber insulation to melt and stick to the screen mesh. The integrated circulating water jacket keeps the cutting chamber cool, enabling uninterrupted 24/7 continuous operation.
④ Italian Airflow Suspension & Specific Gravity Sorting
- Our gravity separation table utilizes Italian aerodynamic suspension technology.
- By synchronizing precise high-frequency eccentric vibration with upward laminar air currents, materials are classified purely by specific gravity: dense copper drops and discharges from the front, while lightweight plastic granules ride the airflow to the rear.
⑤ High-Voltage Electrostatic Separator (100% Metal Recovery)
- Standard granulators on the market typically achieve 95% to 98% purity, losing 3% to 5% of microscopic copper dust and hair wires into the discarded plastic pile.
- Shuliy equips every advanced production line with a high-voltage electrostatic secondary separation roller. Utilizing differential dielectric properties, it extracts residual micro-copper from the rejected plastic stream, achieving an industry-leading standard: No plastic in the copper, and no copper in the plastic.
⑥ Closed-Loop Pulse Jet Dust Collection System
- Enclosed negative-pressure ducting collects airborne fiber, fluff, and micro-dust directly from the crushing and sorting zones.
- The automated pulse-jet reverse cleaning baghouse discharges clean air through top silencers, ensuring full compliance with municipal environmental, health, and safety (EHS) audits.

Technology Comparison: Why Choose a Dry-Type Granulator?
Before purchasing cable recycling equipment, commercial buyers frequently compare dry granulation against wet separation tables and open burning. Here is how they evaluate:
| Evaluation Factors | Shuliy Dry Copper Wire Granulator | Wet Cable Recycling (Water Table) | Open-Air Wire Burning |
|---|---|---|---|
| Environmental Compliance | 100% Eco-Friendly: Zero water consumption, zero wastewater, closed pulse dust control. | Generates heavy chemical sludge, wastewater, and requires environmental permits. | Strictly Illegal: Releases toxic dioxins, furans, and black smoke; risks heavy fines. |
| Copper Quality & Price | Produces bright, unoxidized Millberry copper pellets with high resale value. | Copper oxidizes and blackens in water; requires costly drying before sale. | Severe surface oxidation and ash contamination; fetches the lowest scrap price. |
| Plastic Reusability | Clean, dry PVC/PE pellets can be resold directly to plastic compounders. | Wet plastic sludge requires secondary dehydration, drying, and cleaning. | Plastic insulation is destroyed and lost as toxic fumes. |
| Operational Labor | 1 Operator via automated PLC panel. | 2–3 operators required to handle water basins, sludge, and drying. | Labor-intensive and hazardous to worker health. |

Foire aux questions (FAQ)
Q1: What size screen mesh should I choose for my copper wire granulator?
Screen selection depends on your primary scrap cable wire gauge:
2.0 mm – 2.5 mm Screen: Ideal for ultra-fine telecommunication wires, headphone leads, and hair-thin capillary wires.
3.0 mm – 3.5 mm Screen: The best universal choice for mixed automotive wiring harnesses and household cables.
4.0 mm – 5.0 mm Screen: Recommended for thick commercial industrial cables and copper-aluminum radiator coils.
We supply quick-change screens allowing you to switch mesh sizes within 15 minutes.
Q2: How do I process car wiring harnesses with sticky tape, iron brackets, or brass terminals?
Automotive wire harnesses are notorious for clogging ordinary choppers. The Shuliy copper wire granulator handles electrical tape cleanly thanks to its water-cooled chamber preventing adhesive melting. If your cables contain iron plugs or terminals, we recommend adding our inline magnetic separator ahead of the airflow table to remove all ferrous metals automatically.
Q3: How long do the SKD-11 blades last before sharpening?
Under regular operating conditions with clean copper wire, Shuliy SKD-11 blades process approximately 150 to 200 tons of cable scrap between sharpenings. Knives can be re-sharpened 4 to 6 times using our dedicated blade sharpener before replacement is necessary.
Q4: Can this machine also recycle aluminum wires?
Yes! Our gravity sorting airflow system has variable frequency drives (VFD). Because aluminum is lighter than copper but heavier than plastic, you simply adjust the air volume and vibration frequency to separate aluminum from plastic cable jackets cleanly.
