Modern crushing and sand-making production lines rely on precision-engineered equipment like automatic rail profile machines to optimize raw material processing. These systems integrate seamlessly into aggregate plants, delivering consistent rail head profiling for efficient track maintenance and recycling operations.
The advanced rail profile machine combines hydraulic power with CNC-controlled milling to achieve ±0.5mm accuracy in profile restoration. Key parameters include:
| Parameter | Value |
|---|---|
| Max. Processing Speed | 2m/min |
| Motor Power | 45kW |
| Cutter Diameter | Φ350mm |
| Profile Tolerance | ±0.3mm (EN 13674-1) |
| Dust Extraction Rate | ≥98% |
When installed upstream in sand-making production lines, these machines prepare recycled rail steel for secondary crushing. The precisely profiled scrap metal feeds efficiently into vertical shaft impactors (VSIs) or cone crushers, reducing wear on downstream equipment by up to 30%.
Q: What’s the typical service life of cutting tools?
A: Tungsten carbide cutters last approximately 800-1,200 hours depending on material hardness.
Q: Can it process curved rails?
A: Yes, models with servo-adjustable cutter heads handle radii ≥300m.
Q: How does it connect to screening systems?
A: Standard discharge conveyors (650-1400mm width) interface with vibrating screens.
A 500TPH aggregate plant integrated the rail profiler to process worn mining railway tracks. The system achieved:
– 92% metal recovery rate
– 18% reduction in crusher maintenance costs
– Consistent 0-5mm steel chips for concrete reinforcement applications
The machine’s closed-loop coolant system minimized environmental impact while meeting strict EU noise regulations (<75dB at 1m).
