Ethiopia’s booming construction sector drives demand for high-quality aggregates. A well-designed crushing plant typically includes primary jaw crushers, secondary cone crushers, tertiary impact crushers, and sand-making machines. Key equipment specifications:
| Equipment | Model Example | Capacity (t/h) | Power (kW) |
|---|---|---|---|
| Jaw Crusher | PE600×900 | 50-160 | 75 |
| Cone Crusher | HPT200 | 90-250 | 160 |
| Sand Maker | VSI1140 | 120-220 | 250×2 |
| Vibrating Screen | 3YK2160 | 80-500 | 30×2 |
Basalt and granite dominate Ethiopia’s mineral resources. Primary crushing requires heavy-duty jaw crushers with manganese steel plates (18% Mn content recommended). Secondary processing often employs multi-cylinder hydraulic cone crushers achieving <25mm particle size. For manufactured sand production, vertical shaft impactors with tungsten carbide tips ensure cubic-shaped particles meeting ASTM C33 standards.
Three-deck vibrating screens with polyurethane panels (10mm/20mm/40mm aperture) efficiently separate aggregates into 0-5mm (sand), 5-20mm (concrete aggregate), and 20-40mm (road base) fractions. Modern plants incorporate air classifiers to achieve ≤3% silt content in final products.
Q: What’s the typical production output?
A: A medium plant processes 200-300tph, yielding ~30% sand and 70% aggregates.
Q: How to handle power fluctuations?
A: Diesel generators (400kVA backup recommended) supplement grid power.
This Addis Ababa-based operation processes 800t
