Leading calcite crushing machine manufacturers specialize in designing robust equipment for sand and aggregate production lines. These machines process calcite ore into high-quality construction materials, meeting global standards for concrete, asphalt, and infrastructure projects.
A typical production line includes:
1. Jaw Crusher: Primary crushing (Feed size: ≤1,200mm; Output: 10-350mm)
2. Impact Crusher/Cone Crusher: Secondary crushing (Output: ≤30mm)
3. VSI Sand Maker: Tertiary shaping (0-5mm artificial sand)
4. Vibrating Screen: Multi-layer grading
| Equipment | Model Example | Capacity (t/h) | Power (kW) |
|---|---|---|---|
| Jaw Crusher | PE-600×900 | 50-160 | 55-75 |
| Cone Crusher | HPT300 | 120-340 | 315 |
| VSI Crusher | S8-1145 | 100-260 | 250×2 |
Q: What’s the lifespan of calcite crushers?
A: 3-5 years with proper maintenance; wear parts (e.g., blow bars) require replacement every 500-800 hours.
Q: How to control dust pollution?
A: Integrated water spray systems + pulse bag filters reduce dust to <20mg/m³.
A Malaysian client processed 500TPH calcite ore into 0-4.75mm sand and 5-20mm aggregate using:
– Primary PE1200×1500 jaw crusher
– Secondary HST315 cone crusher + S8 VSI crusher
Final products achieved ASTM C33 gradation standards for commercial concrete.
