Rio Tinto’s iron ore beneficiation process involves advanced crushing and sand-making technologies to produce high-quality aggregates. The core equipment includes jaw crushers, cone crushers, vertical shaft impactors (VSIs), and vibrating screens, ensuring efficient particle size reduction and grading.
| Equipment | Model | Capacity (t/h) | Power (kW) |
|---|---|---|---|
| Jaw Crusher | C6X160 | 800-1200 | 160 |
| Cone Crusher | HPT300 | 200-500 | 315 |
| VSI Crusher | B9100SE | 300-600 | 400 |
| Vibrating Screen | S5X3075-3T | 500-800 | 30 |
1. Primary Crushing: Iron ore is fed into a jaw crusher for coarse crushing.
2. Secondary Crushing: Cone crushers refine the material to ≤50mm.
3. Sand Making: VSIs shape the particles into cubic sand (0-5mm).
4. Screening: Multi-layer screens classify aggregates by size for end-use applications.
Q: How to reduce wear in VSI crushers?
A: Use tungsten carbide tips and optimize feed size (≤45mm).
Q: What’s the ideal moisture content for screening?
A: Below 3% to prevent clogging.
