A modern concrete crushing and sand-making production line integrates primary crushing, secondary crushing, screening, and sand shaping to produce high-quality aggregates for construction. The core equipment includes jaw crushers, cone crushers, impact crushers (for shaping), vibrating screens, and sand washers.
| Equipment | Model | Capacity (t/h) | Power (kW) |
|---|---|---|---|
| Jaw Crusher | PE-600×900 | 50-120 | 75 |
| Cone Crusher | HPT300 | 120-250 | 315 |
| Vertical Shaft Impact Crusher | VSI1140 | 180-380 | 440 |
Raw concrete waste is fed into the jaw crusher for primary crushing. The output material (≤200mm) enters the cone crusher for secondary reduction. After screening, oversized particles are recirculated while qualified aggregates proceed to the VSI crusher for sand shaping. Final products include 0-5mm manufactured sand, 5-10mm, 10-20mm, and 20-31.5mm gravel.
Q: How to control aggregate needle content?
A: Use multi-stage crushing with cone+VSI configuration and adjust cavity parameters.
Q: Dust control measures?
A: Install water spray systems at transfer points and use bag filters.
Q: Typical energy consumption?
A: Approximately 1.8-2.5 kWh per ton of finished product.
Location: Hamburg, Germany
