A modern crushing and sand-making production line integrates coarse crushing, fine crushing, sand shaping, and screening to produce high-quality aggregates for construction, road building, and concrete applications. Key equipment includes jaw crushers, cone crushers, impact crushers (for shaping), vibrating screens, and sand washers.
| Equipment | Model | Capacity (t/h) | Power (kW) |
|---|---|---|---|
| Jaw Crusher | PE-600×900 | 50-120 | 75 |
| Cone Crusher | HPT300 | 120-250 | 315 |
| Vertical Shaft Impact Crusher | VSI1140 | 200-380 | 440 |
| Screening Machine | 3YK3070 | 80-150 | 22×2 |
Raw materials are fed into the jaw crusher for primary crushing. The output is conveyed to secondary crushing (cone crusher) and then to the sand maker for shaping. Screens classify particles into 0-5mm (mechanism sand), 5-10mm, and 10-20mm aggregates.
Q: What’s the lifespan of wear parts?
A: Jaw plates last ~200k tons; cone mantles ~150k tons under normal conditions.
Q: Dust control solutions?
A: Wet dust suppression systems or bag filters reduce PM10 emissions by 90%.
