Impact crushers serve as the backbone of contemporary sand and aggregate processing plants, offering high reduction ratios and cubical end products. These machines utilize kinetic energy to fracture materials between blow bars and impact plates, making them ideal for limestone, concrete recycling, and manufactured sand applications.
| Model | Rotor Size (mm) | Max Feed (mm) | Capacity (t/h) | Power (kW) |
|---|---|---|---|---|
| CI5X1520 | 1500×2000 | 800 | 500-700 | 400-630 |
| PFW1315III | 1300×1500 | 700 | 180-320 | 220-315 |

When designing a complete crushing circuit:
1. Primary crushing typically uses jaw crushers
2. Secondary/tertiary stages employ cone or impact crushers
3. Vertical shaft impactors (VSI) optimize particle shape for concrete sand
Q: How often should wear parts be replaced?
A: Blow bars typically last 100-300 hours in abrasive applications; regular inspection is critical.
Q: Can impact crushers handle wet material?
A: While possible, moisture content above 5% significantly reduces capacity and accelerates wear.
A 250tph plant configuration:
– Primary: JC546 jaw crusher
– Secondary: CI5X1520 impact crusher
– Tertiary: VSI1140 sand maker
Final products achieved 95% cubicity rating for premium concrete aggregate specifications. The system maintains consistent production despite fluctuating feed sizes through hydraulic adjustment mechanisms.
