With limestone quarries becoming scarce in Anno 2070, the construction industry must adapt by optimizing crushed stone and sand production lines. Modern equipment focuses on energy efficiency, low waste, and high yield to meet demand sustainably.
1. Jaw Crusher (Primary Crushing)
– Model: JC-120
– Feed Size: ≤750mm
– Capacity: 150-350 TPH
– Power: 90-160 kW
2. Impact Crusher (Secondary Crushing)
– Model: IC-80
– Output Size: 0-40mm Adjustable
– Capacity: 100-250 TPH
3. VSI Sand Maker (Tertiary Processing)
– Model: VSI-900
– Sand Yield: 50-120 TPH
– Fineness Modulus: 2.6-3.0
| Equipment | Power (kW) | Output Size (mm) | Noise Level (dB) |
|—————-|———–|——————|——————|
| Jaw Crusher | 90-160 | ≤200 | ≤75 |
| Impact Crusher | 110-185 | ≤40 | ≤80 |
| VSI Sand Maker | 132-220 | ≤5 | ≤70 |
Q1: Can recycled concrete replace limestone aggregates?
*A1:* Yes, with proper crushing/screening, recycled concrete achieves comparable strength (30-40 MPa).
Q2: How to reduce dust in dry production?
*A2:* Install pulse bag filters (+99% efficiency) and water mist systems.
A coastal city replaced limestone with demolished concrete waste:
– Line Configuration: Mobile jaw crusher + tracked screen + VSI crusher
– Output: 180 TPH of 0-4.75mm sand & 5-20mm gravel
– Savings: Reduced transport costs by 35% vs. distant quarries.
This approach demonstrates viability in resource-scarce scenarios while maintaining ISO-certified aggregate quality
