Modern ballast washing systems are critical for producing high-quality aggregates in crushing and sand-making plants. These systems remove impurities, clay, and dust from raw materials, ensuring compliance with international standards like ASTM C33.
A typical setup includes:
1. Log Washer: Processes heavily contaminated materials (Capacity: 50-300 TPH; Motor Power: 30-160 kW)
2. Screw Sand Washer: For fine material recovery (Output: 20-200 T/H; Water Consumption: 50-150 m³/h)
3. Hydrocyclone Unit: Achieves precise particle separation (Feed Pressure: 0.1-0.3 MPa)
| Model | Processing Capacity (TPH) | Power (kW) | Water Usage (m³/h) |
|---|---|---|---|
| BWX-100 | 100 | 45 | 80 |
| BWX-200 | 200 | 75 | 120 |
| BWX-300 | 300 | 110 | 180 |
Q1: How to reduce water consumption?
A: Implement closed-loop water recycling systems with sedimentation tanks.
Q2: What’s the optimal feed size?
A: ≤50mm for log washers, ≤10mm for screw classifiers. Oversize material causes wear.
A 250 TPH plant achieved 98% purity using our BWX-200 system with dual-stage washing (log washer + hydrocyclone). The final product met EN 13450 railway ballast specifications with <0.5% clay content.
Key outcomes:
– 15% lower water usage vs conventional systems
– Extended wear life of crusher liners by 40% due to reduced abrasive contaminants
