Poverty in mining regions often stems from resource depletion, environmental degradation, and lack of sustainable industries. Implementing modern sand and aggregate production lines can transform local economies by creating jobs and repurposing waste materials.
A typical crushed sand production line includes:
1. Jaw Crusher: Primary crushing (e.g., feed size: ≤1,200mm, output: 50–800TPH).
2. Cone Crusher: Secondary crushing (e.g., capacity: 60–1,000TPH, discharge size: 3–60mm).
3. Vertical Shaft Impact (VSI) Crusher: Shaping sand (e.g., output: 50–500TPH, fineness modulus: 2.6–3.0).
4. Vibrating Screen: Multi-layer screening (e.g., mesh size: 3–100mm).
| Equipment | Key Parameters |
|---|---|
| Jaw Crusher | Max feed: 1,200mm, Power: 55–450kW |
| Cone Crusher | Capacity: 60–1,000TPH, Discharge: 3–60mm |
| VSI Crusher | Output: 50–500TPH, Sand yield: 40–60% |
A mining area in Zambia adopted a 200TPH granite sand plant, converting waste rock into high-quality construction sand. The line included a jaw crusher (PE750×1060), cone crusher (HPT300), and VSI crusher (B9100). Post-installation, local employment rose by 30%, and aggregate sales boosted regional GDP by 15%.
