The Aggregate Industry in Vanuatu: Key Equipment and Practices
Vanuatu’s construction sector relies heavily on high-quality aggregates for infrastructure projects, including roads, ports, and buildings. With limited natural sand resources, the demand for manufactured sand (M-Sand) and crushed stone has grown, making crushing and screening equipment essential for local operators.
1. Jaw Crushers: Primary crushing of hard rocks (e.g., basalt) into coarse aggregates.
2. Cone/Impact Crushers: Secondary crushing to produce finer particles for concrete or asphalt.
3. VSI Crushers: Tertiary stage for shaping M-Sand with optimal gradation.
4. Vibrating Screens: Classify aggregates by size (e.g., 0–5mm, 5–20mm).
5. Log Washers: Remove clay or impurities from raw materials.
Q: What’s the ideal crusher for volcanic rock?
A: A jaw crusher (for primary) + cone crusher (for secondary) handles basalt efficiently.
Q: How to reduce dust in crushing plants?
A: Use water sprays, enclosures, or bag filters.
Q: Can recycled concrete be used?
A: Yes, but pre-screening to remove rebar is critical.
A local contractor deployed a 150tph mobile crushing plant (jaw + impact crusher + screen) to process basalt for road base. The project achieved 95% compliance with ASTM C33 standards, reducing reliance on imported aggregates.
For mining associations in Vanuatu, partnering with global equipment suppliers and adopting tailored solutions will be key to meeting the nation’s growing infrastructure needs.
