真空分离炉 · Flagship
Overview
Separates zinc from copper-zinc brass scrap under vacuum. Copper stays in the crucible and is tapped clean; zinc is distilled off and recovered as metal, not as oxide dust.
Applications
- Brass scrap & turnings
- Copper-zinc dross
- Galvanizing residues
- Precious-metal bearing copper
Key points
Why it earns its place on your floor
Zinc leaves as metal, not as dust
Zinc is drawn off as vapour and condensed back into saleable metal, so you are not losing it into the baghouse.
Clean copper, tapped straight out
With the zinc removed, the copper stays inside the crucible and is tapped at a grade you can sell without discount.
One run instead of two
Vacuum separation replaces the separate melting and dressing steps, cutting both energy and labour per tonne.

| Processing principle | Vacuum distillation — zinc evaporates and is condensed back into metal |
|---|---|
| Feed materials | Brass scrap, copper-zinc mixed material, zinc-bearing residues |
| Metal recovery | Copper retained in the crucible; zinc recovered; gold and silver recovered with the copper |
| Model | SMJD-3000T / SMJD-6000T |
| Typical capacity | SMJD-3000T: 2+ tonnes per batch; SMJD-6000T: 4+ tonnes per batch |
| Cycle time | Aluminium-zinc: approx. 3 hours per batch. Copper-zinc: approx. 3 batches per 24 hours (varies with material, typically ±1 hour) |
| Output | SMJD-3000T: approx. 10 tonnes per 24 hours |
| Energy consumption | Approx. 700–900 kWh per tonne |
| Installed power | 300–500 kW, built to order |
| Transformer | 500 kVA |
| Working temperature | Approx. 1100 °C measured at the thermocouple |
| Pump-down time | Approx. 5 hours to reach working vacuum |
| Crucible | Graphite-silicon carbide; 30–80 heats (depends on ramming practice); replacement approx. CNY 20,000 / approx. 2 days |
| Cooling | Open-circuit cooling tower: approx. 150 T for SMJD-3000T, approx. 180 T for SMJD-6000T |
| Separation result | Copper product: approx. 1% residual zinc. Zinc product: ≤1% residual copper |
| Gold & silver | Gold and silver report to the copper; overseas feed typically approx. 3 g Au and 500 g Ag per tonne |
| Export destinations | Korea, Thailand, Malaysia, Laos, Vietnam, Russia, Kazakhstan and more |
