Gravel mining disrupts natural succession by removing topsoil and altering hydrological patterns. However, modern crushing/screening equipment minimizes environmental impact through precision processing. Our turnkey sand/aggregate production lines feature closed-loop water systems and dust suppression tech to accelerate site rehabilitation.
1. Primary Jaw Crusher
– Model: JC-120
– Feed size: ≤650mm
– Capacity: 150-300TPH
– Power: 132kW
2. Secondary Cone Crusher
– Model: CC-200
– Closed-side setting: 19-38mm
– Throughput: 180TPH
3. Tertiary VSI Crusher
– Model: VSI-850
– Max feed: 50mm
– Sand yield: 60%
Our optimized flow:
Raw feed → Scalping → Primary crushing → Secondary crushing → Screening → Tertiary shaping → Sand washing → Stockpiling
Key innovations:
– Multi-stage screening reduces waste
– AI-powered load distribution
– Noise-controlled below 75dB
Q: How to control dust during gravel processing?
A: Our lines integrate mist cannons + bag filters (99% efficiency).
Q: Minimum recovery time post-mining?
A: With our restoration package, vegetation returns in 12-18 months.
