Crushing and Sand-Making Equipment in the Aggregates Industry
The aggregates industry plays a pivotal role in global infrastructure development, supplying materials like sand, gravel, and crushed stone for construction, roads, and concrete production. Central to this sector are crushing and sand-making machines, which transform raw rock into high-quality aggregates with precise gradation.
1. Jaw Crushers: Primary crushers for coarse reduction of hard rocks (e.g., granite, basalt). Their rugged design ensures high throughput with minimal maintenance.
2. Cone Crushers: Secondary/Tertiary crushers for finer crushing. Ideal for producing uniform cubical aggregates.
3. Impact Crushers: Versatile machines for soft-to-medium-hard rocks, excelling in shaping aggregates (e.g., limestone recycling).
4. Sand Makers (VSI/HVI): Critical for artificial sand production, optimizing particle shape and gradation to meet concrete standards.
Q: How to minimize dust in crushing plants?
A: Use water sprays, enclosures, or dust suppression systems alongside bag filters.
Q: What’s the lifespan of wear parts?
A: Varies by material; manganese jaws last 500–1,000 hours in granite applications. Regular inspection is crucial.
Q: Can recycled concrete be processed?
A: Yes—impact crushers are preferred for removing rebar and achieving clean aggregates.
