Modern stone crusher machines are engineered to deliver high-capacity crushing for aggregate production. Key equipment includes jaw crushers, cone crushers, impact crushers, and sand-making machines, each playing a critical role in transforming raw stone into graded sand and gravel.
| Equipment | Capacity (t/h) | Power (kW) | Feed Size (mm) |
|---|---|---|---|
| Jaw Crusher | 50-800 | 55-250 | ≤1200 |
| Cone Crusher | 30-1000 | 90-315 | ≤350 |
| Impact Crusher | 60-500 | 132-400 |
A typical sand and gravel production line consists of:
1. Primary crushing (Jaw Crusher)
2. Secondary crushing (Cone/Impact Crusher)
3. Sand shaping (VSI Sand Maker)
4. Screening and washing
Q: How to choose a crusher for hard rock?
A: Opt for a hydraulic cone crusher with wear-resistant liners (>500 Brinell hardness).
Q: What’s the output size range?
A: Adjustable from 0-5mm (sand) to 10-40mm (gravel).
