The Bukit Ibam iron ore project requires a high-efficiency crushing and sand-making production line to process raw iron ore into graded aggregates. The proposed system integrates jaw crushers, cone crushers, vertical shaft impactors (VSI), and screening equipment to achieve optimal particle size distribution for downstream applications.
| Equipment | Model | Capacity (t/h) | Power (kW) |
|---|---|---|---|
| Primary Jaw Crusher | CJ612 | 400-600 | 110 |
| Secondary Cone Crusher | CH660 | 250-350 | 315 |
| Tertiary VSI Crusher | CV218 | 150-300 | 250 |
| Vibrating Screen | SF1860-3D | 400-500 | 22×2 |
The three-stage crushing system reduces iron ore from 800mm feed size to 0-5mm manufactured sand. Primary crushing adopts heavy-duty jaw crushers for coarse reduction, followed by hydraulic cone crushers for intermediate crushing. The VSI crusher performs final shaping to produce cubical aggregates meeting ASTM C33 standards.
Q: What’s the expected service life of wear parts?
A: Jaw plates last 6-8 months, cone liners 4-6 months under normal iron ore processing conditions.
Q: How to control dust emission?
A: The system includes water spray nozzles at transfer points and bag filters for dust collection.
A similar installation in Terengganu processes 1.2MTPA iron ore with identical equipment configuration, achieving:
– Final product yield: 85% (0-5mm sand)
– System availability: 92%
