Iron ore beneficiation plants are critical for upgrading low-grade ore into high-quality raw materials for steel production. A well-designed crushing and sand-making line ensures efficient processing, reducing waste and maximizing resource utilization.
1. Primary Jaw Crusher: Handles large-sized iron ore (≤1200mm), with a capacity of 50-800 TPH. Output size: 150-300mm.
2. Secondary Cone Crusher: Fine crushing to 20-70mm, equipped with hydraulic adjustment for precise control.
3. Tertiary Impact Crusher/VSI Sand Maker: Produces 0-5mm sand for concrete or asphalt aggregates. VSI crushers achieve high cubicity (≥90%).
| Equipment | Model Example | Capacity (TPH) | Power (kW) |
|---|---|---|---|
| Jaw Crusher | PE750×1060 | 80-220 | 110 |
| Cone Crusher | HPT300 | 90-350 | 315 |
| VSI Crusher | S8-1145 | 100-260 | 250×2 |
Vibrating screens (e.g., 3YK3070) separate crushed ore into fractions, while log washers remove clay impurities. Sand recovery units recycle fine particles (>0.075mm) with >95% efficiency.
Q: How to reduce over-crushing?
A: Optimize crusher settings and adopt multi-stage screening.
Q: What’s the lifespan of wear parts?
A: Mn18Cr2 jaw plates last ~6 months under 500 TPH workload; VSI rotors require replacement every 800-1200 hours.
A 500 TPH plant achieved 28% Fe grade improvement using
