Why dry separation lines lead this market
Dry physical separation — shredding, pulverizing, then air and electrostatic separation — recovers copper and mixed metals from boards without the water, permits and chemical risk of wet processes. The metal fraction sells to smelters; the resin powder goes to molding or disposal buyers.
Key parameters to define
- Feed: bare PCBs, whole boards with components, or mixed e-waste.
- Daily volume and how consistently you can collect it.
- Target: copper-rich mixed metal fraction or further refined streams.
- Dust and emission control standard required at your site.
- Whether dismantling/pre-sorting happens before the line.
Typical configuration ranges
| Stage | Function | Indicative range |
|---|---|---|
| Shredding | Primary size reduction of boards | 300 kg/h – 1 t/h |
| Pulverizing | Fine grinding to liberate metal from resin | Matched to shredder |
| Separation | Air classification + electrostatic | 95%+ metal recovery class |
| Dust control | Pulse collectors, sealed conveyors | Included in line scope |
Ranges are indicative. Recovery depends on board type and pre-sorting discipline.
What a quotation should clarify
| Quotation area | Questions to record |
|---|---|
| Feed basis | What board types is the recovery figure measured on? |
| Recovery | Metal recovery rate and fraction purity, with test data? |
| Resin | What happens to the non-metal fraction — is there a buyer route? |
| Wear | Pulverizer wear-part life on glass-fiber boards? |
| Compliance | Emission documentation for your local e-waste rules? |
