The wire and cable shredder is an industrial-grade unit engineered for the mechanical size-reduction of scrap and waste cables-data, communication or power. It sheaths, chops and liberates conductive cores (copper/aluminium) from their plastic or rubber insulation in a single pass, creating clean, separable fractions. The result: high-value metals ready for smelting and plastics fit for resale, delivering maximum recovery and revenue from every kilo of cable.
1. Over 99% Copper Purity: The pre-shredder + granulator separates insulation from metal in a single pass, achieving LME grade standards.
2. High-torque, low-speed cutters reduce power consumption by 25% and keep noise levels below ≤ 75 dB, while handling armored cables or wire harnesses with diameters less than 50mm.
3. Modular Cutters and Screens: 8-40 mm screens can be changed in 5 minutes, switching from busbar cutting to fine copper granules; four-edged reversible blades last for 1200 tons before regrinding.
4. Safety: Automatic reverse, anti-winding feeding device, and CE/UL safety circuits compliant with Cat. 3 standards.
5. Fast Return on Investment: 35-40 kg of copper can be recovered from every 100 kg of cable; with current high copper prices, the typical payback period is 8-10 months.
Product Applications
RITECH's purpose-engineered Industrial Copper Pre-Shredder is the first-cut solution for every grade of electrical cable-from fine wiring harnesses to heavy, armored power cores-liberating clean copper in a single pass.
How to Choose the Right Copper Wire Granulator (Wire Shredder)?
- Wire Range: From fine wire bundles of 0.1 mm to power cables with a diameter of 30 mm? If the average diameter is > 15 mm, choose a model with ≥ 45 kW.
- Contaminants: Steel armor, plugs, or only PVC? If the iron content is > 3%, a cross-belt magnetic separator and pre-shredder are needed.
- Input Volume: 100 kg/h workshop → 20-40 kg/h tabletop equipment; 1 t/h recycling plant → 70-90 kW integrated production line.
- 99.9% copper for sale to smelters → Choose an air separation table + turbine refining stage.
- 98% copper for internal casting → A single-stage air gravity separator is sufficient, saving 8 kW of power.
- Rotor: One-piece forged construction, no welding, 55 HRC blades; equipped with at least 3 rotating blades for shredding film insulation materials.
- Screen: Stainless steel material, quick-change; spare 8mm, 12mm, and 20mm screens available for processing different batches of materials.
- Motor and Transmission: IE3 high-efficiency motor, V-belt drive instead of direct drive to absorb shock; variable speed function optional for processing different types of cables.
- Send a 50 kg sample; reputable suppliers will provide a production report within 48 hours, showing the percentage of copper content and energy consumption per ton of plastic (kWh/ton).
- Request wiring compliant with CE/UL standards, noise reports, and reports showing dust emissions below 1 mg/m³ to avoid future EPA issues.
- Pricing guidelines: Desktop machine 20 kg/hour ≈ $6000; 500 kg/hour production line ≈ $45000; 1 ton/hour (with pre-shredder) ≈ $85000.
- Spare parts kit (20 blades, 2 screens, belts) should cost less than 8% of the machine cost and be readily available.
- Warranty: At least 12 months warranty on the shredding chamber, lifetime technical support, and video service within 4 hours.
By following these five steps, you will purchase a granulator that pays for itself in months, not years.
