Cable Wire Strippers vs. Copper Granulators: Best Equipment for Scrapyards
Published on September 05, 2026 by MillberryCopper.com Trade Intelligence Desk
Key Takeaways & Summary
Compare processing speed, labor costs, and ROI for heavy industrial cable strippers vs air gravity separator copper granulator machines.
When to Use Heavy Duty Cable Stripping Machines
For heavy armored power cables, submarine cables, and thick single-core conductors (>5mm diameter), rotary blade stripping machines offer the highest throughput with minimal energy consumption, generating pristine, unbent Millberry wire with zero copper loss.
Air Vibration Copper Granulator Systems for Wire Harnesses
Automotive wiring harnesses, communications cables, and tangled multi-strand cords cannot be efficiently stripped manually. Industrial granulators shred cables into fine particles, separating copper granules from plastic insulation using zig-zag air classifiers and water/air shaker tables with 99.8% recovery rates.
Calculating Scrap Processing Yields & Labor Costs
A modern compact granulator processing 300 to 500 kg/hour of mixed cable pays for itself within 4 to 6 months by upgrading low-value insulated copper wire ($3.50/kg) into high-value copper chops and Millberry equivalents ($9.50/kg).
Equipment Maintenance & Blade Replacement Guidelines
Tungsten carbide and high-speed steel (D2) blades require periodic sharpening every 150 operating hours. Maintaining sharp cutting clearances reduces dust generation and prevents insulation plastic from fusing with copper granules.
