| Best application | Clean, uniform cables with known diameters | Mixed insulated copper wire and small cable | High-volume, mixed cable streams and continuous operation | Input material range, insulation types, contamination level, and required output purity |
| Typical throughput | Approximately 20–150 kg/h | Approximately 100–1,000 kg/h | Approximately 500–3,000+ kg/h | Confirm tested capacity for the actual cable mix rather than relying only on maximum rated capacity |
| Copper recovery target | Up to about 98% when cable size and feed rate are consistent | Commonly about 95–99% with correctly adjusted air separation | Commonly about 97–99% after coordinated shredding, separation, and screening | Request a material test report defining recovery rate, copper purity, and test conditions |
| Key safety features | Fixed guards, emergency-stop button, protected feed opening, and overload protection | Interlocked access doors, emergency stops, overload protection, guarded belts, and enclosed rotating parts | Safety-rated interlocks, lockout points, emergency-stop circuit, guarded conveyors, access platforms, and dust-control safeguards | Check the risk assessment, emergency-stop validation, guarding design, and lockout/tagout provisions |
| Noise and dust control | Usually limited dust; noise depends on motor and stripping speed | Requires enclosed transfer points and may require local exhaust ventilation | Typically requires a designed dust-collection system, ducting, filters, and noise-control measures | Ask for measured sound pressure levels, dust-emission data, filter specifications, and workplace exposure controls |
| Routine maintenance | Daily cleaning; frequent blade, roller, and cable-diameter adjustments | Daily cleaning; regular blade inspection; lubrication and filter inspection according to operating hours | Daily inspection plus scheduled servicing of cutters, bearings, screens, conveyors, magnets, fans, and filters | Obtain the preventive-maintenance schedule, spare-parts list, lubrication chart, and expected wear-part life |
| Energy considerations | Generally the lowest installed power; suitable for intermittent processing | Often about 30–100 kW for a complete compact system, depending on capacity | Often above 100 kW because of shredding, conveying, separation, and dust collection | Compare kWh per tonne at the same feed composition and include standby and dust-collection loads |
| Environmental compliance | Low process complexity; still requires compliant electrical equipment and waste handling | Requires control of airborne dust, noise, residual insulation, and electrical consumption | Requires documented controls for dust, noise, waste residues, stormwater, energy use, and occupational exposure | Confirm applicable local permits, waste codes, air-emission limits, noise limits, and electrical requirements |
| Electrical and conformity documentation | Electrical schematic, motor data, operating manual, and conformity declaration | Complete wiring documentation, control-panel details, conformity declaration, and test records | System risk assessment, electrical drawings, safety-circuit validation, manuals, and commissioning records | Select documentation appropriate to the installation country; do not treat a generic certificate as full compliance |
| Recommended buyer profile | Small processors prioritizing low cost, simple operation, and manual sorting | Recyclers needing flexible processing with moderate capital and floor-space requirements | Facilities with stable feed volume, trained maintenance staff, and sufficient utility capacity | Match the machine to annual tonnes, available labor, floor space, budget, and permit conditions |
