The rise in illegal mining fatalities in Ghana highlights the urgent need for regulated, mechanized crushing systems. Properly designed sand and gravel production lines can replace hazardous manual operations while boosting output efficiency.
A complete crushing line typically includes:
1. Primary Jaw Crusher (PE-600×900)
– Feed opening: 600×900mm
– Capacity: 50-160t/h
2. Secondary Cone Crusher (HPT300)
– Max feed size: 240mm
– Discharge range: 16-38mm
3. Vertical Shaft Impact Crusher (VSI-1140)
– Throughput: 120-220t/h
– Sand yield: 30-50%
| Equipment | Model | Power(kW) |
|---|---|---|
| Vibrating Feeder | GZD960×3800 | 11 |
| Jaw Crusher | PE600×900 | 75 |
| Cone Crusher | HPT300 | 315 |
| VSI Crusher | VSI1140 | 440 |
Q1: What’s the minimum investment for a legal crushing plant?
A: Approximately $150,000 for a 50t/h setup including dust control systems.
Q2: How to prevent dust pollution?
A: Water spray systems + bag filters reduce dust to <20mg/m³.
