Singapore’s construction boom drives demand for high-quality sand and granite aggregates. Leading importers supply specialized crushing plants to produce precisely graded materials for concrete, asphalt, and infrastructure projects.
Modern crushing lines integrate:
– Jaw Crushers: Primary reduction (e.g., 600x900mm feed opening, 75-200tph capacity)
– Cone Crushers: Secondary/tertiary crushing (e.g., HP300 with 220kW motor, CSS 6-38mm)
– Vertical Shaft Impactors (VSI): Sand shaping (Rotor speed 1,500-2,800rpm, 5mm graded output)
– Vibrating Screens: Multi-deck classification (3YK3070 with 50-800tph capacity)
| Equipment | Key Parameter | Output Size |
|---|---|---|
| Jaw Crusher | Feed: ≤750mm | 60-150mm |
| Cone Crusher | Power: 160-315kW | 10-40mm |
| VSI Crusher | Throughput: 120-400tph | 0-5mm (sand) |
Advanced systems incorporate dust suppression (water spray at 10L/min per crusher), noise enclosures (<75dB), and automated grading controls via PLC. Modular designs enable rapid deployment for Singapore’s space-limited sites.
Q: What’s the typical granite-to-sand yield ratio?
A: ~60% aggregates + 30% sand (+10% fines). VSI optimization improves sand output.
Q: How to mitigate abrasive wear in tropical conditions?
A: Tungsten carbide tips (VSI rotors), Mn18Cr2 jaw plates (~20,000hr lifespan).
