Iron ore processing begins with primary crushing of run-of-mine (ROM) material. A well-designed crushing circuit ensures optimal size reduction, energy efficiency, and minimal downtime. Key equipment includes jaw crushers, cone crushers, and vibrating screens.
| Equipment | Model | Capacity (t/h) | Power (kW) |
|---|---|---|---|
| Jaw Crusher | PE-900×1200 | 220-450 | 110-132 |
| Cone Crusher | HPT300 | 200-500 | 250-315 |
| Vibrating Screen | 3YK3070 | 100-600 | 15-37 |
1. Primary Crushing: ROM ore (<800mm) is reduced to <200mm using a jaw crusher.
2. Secondary Crushing: Cone crushers further crush material to <50mm.
3. Screening: Vibrating screens separate fines (<10mm) for pelletizing or sintering.
Q: How to minimize wear in iron ore crushing?
A: Use high-manganese steel liners and regular lubrication.
Q: What’s the ideal moisture content for crushing?
A: Below 5% to prevent clogging and improve efficiency.
Project: Australia Iron Ore Mine
Solution: Two-stage crushing (Jaw + Cone) with a 500t/h capacity. Achieved 98% availability and 20% lower energy consumption vs. traditional setups.
