Coal mining and aggregate production rely on robust crushing and screening systems. Key equipment includes jaw crushers, cone crushers, impact crushers, vibrating screens, and belt conveyors – all working in tandem to process raw materials into specified sizes.
| Equipment | Model | Capacity (t/h) | Power (kW) |
|---|---|---|---|
| Jaw Crusher | PE-600×900 | 50-160 | 75 |
| Cone Crusher | PYB1750 | 215-390 | 160 |
| Impact Crusher | PF-1315 | 130-250 | 220 |
| Vibrating Screen | 3YK1860 | 50-500 | 18.5×2 |
Multi-deck vibrating screens separate crushed materials into precise gradations while heavy-duty belt conveyors transport materials between processing stages. Modern systems incorporate dust suppression and noise reduction technologies.
Q: What’s the typical lifespan of crusher wear parts?
A: Jaw plates last 3-6 months depending on material hardness; cone mantles 4-8 months with proper maintenance.
Q: How to choose between cone and impact crushers?
A: Cone crushers suit harder materials; impact crushers better for shaping softer aggregates.
