Ethiopia’s construction boom demands high-quality gravel and sand aggregates. A well-designed crushing line typically includes:
1. Primary Jaw Crusher (e.g., PE-600×900)
– Feed opening: 600×900mm
– Capacity: 50-160 t/h
– Power: 55-75kW
2. Secondary Cone Crusher (e.g., HPT300)
– Max feed size: 240mm
– Capacity: 120-400 t/h
– Closed-side setting: 19-51mm
3. Tertiary Impact Crusher (for shaping)
4. Vibrating Screens (3-4 deck options)
A 150tph granite processing line in Addis Ababa uses:
– Raw material size: ≤500mm
– Finished products:
– 0-5mm (mechanism sand)
– 5-10mm
– 10-20mm
– 20-31.5mm
Equipment List:
| Equipment | Model | Power | Output Size |
|———–|——-|——-|————|
| Vibrating Feeder | GZD960×3800 | 11kW | N/A |
| Jaw Crusher | PE600×900 | 75kW | ≤130mm |
| Cone Crusher | HPT200 | 160kW | ≤38mm |
| Sand Maker | VSI1140 | 250kW | ≤5mm |
Q1: What’s the lifespan of wear parts?
A: Jaw plates last ~6 months in granite crushing; cone mantles ~4,000 hours.
Q2: Dust control solutions?
A: Wet suppression systems reduce dust by 80%. Enclosed conveyors are recommended.
Awash River Gravel Plant (2023)
– Capacity: 200tph
– Equipment Used: Mobile crushing station (KE750-1 + KH300-II)
