A copper slag granulation plant transforms molten slag into high-quality sand and aggregate for construction applications. The process involves rapid cooling, crushing, screening, and grading to produce uniform particles with excellent mechanical properties.
1. Granulator: Water-quenches molten slag (1,200–1,300°C) at 10–15 tons/hour capacity.
2. Jaw Crusher: Primary reduction to ≤50mm (Model JC56, 90kW motor).
3. Cone Crusher: Secondary crushing to ≤20mm (Model CC200, 160kW).
4. VSI Crusher: Tertiary shaping for cubical grains (Model VSI-800, 250kW).
5. Screening System: Multi-deck vibratory screens (3–5mm/5–10mm/10–20mm fractions).
| Product | Size Range | Bulk Density | Abrasion Value (%) |
|---|---|---|---|
| Fine Sand | 0-3mm | 1.6t/m³ | <25 |
| Coarse Sand | 3-5mm | 1.7t/m³ | <22 |
| Aggregate | 5-20mm | 1.8t/m³ | <18 |
A 50tph plant installed in 2022 processes copper slag from a local smelter:
– Input: Molten slag @12tph
– Output: 35% fine sand, 45% coarse sand, 20% aggregate
– End-use: Ready-mix concrete and road base materials
Q: What’s the lifespan of wear parts?
A: Jaw plates last ~6 months, cone liners ~9 months with proper maintenance.
Q: Can it process other slags?
A: Yes
