The 1100 primary impact crusher is a high-capacity crushing machine specifically engineered for the first stage of size reduction in quarries, mines, and recycling operations. The designation “1100” refers to a 1100 mm rotor diameter or feed opening, allowing the machine to handle large input materials efficiently.

2. Technical Specifications

  • Rotor Diameter: ~1100 mm

  • Max Feed Size: Up to 500–800 mm

  • Capacity: 150–300 tph (depending on material)

  • Crushing Ratio: High

  • Output Size: Adjustable, typically 0–60 mm

  • Wear Liners: Replaceable manganese alloy

  • Rotor Type: Heavy-duty, reversible

3. How It Works

  1. Feeding: Raw material is fed into the crusher.

  2. Impact: The rotor’s blow bars fling the material against fixed impact curtains.

  3. Breaking: The rock breaks due to the high-energy collision and shattering effect.

  4. Recirculation: The material may re-enter the rotor zone for secondary reduction.

  5. Discharge: Final product exits through the bottom conveyor.

4. Advantages

  • Excellent cubic-shaped aggregate output

  • High throughput and efficiency

  • Easy maintenance (hydraulically opening housing)

  • Adjustable product size

  • Cost-effective (long-life wear parts)

5. Application Areas

  • Quarries: Limestone, granite, basalt, dolomite

  • Recycling plants: Concrete and asphalt waste

  • Mining: Ore and hard rock preparation

  • Construction: Road base, infrastructure

  • Mobile crushers: In-situ crushing tasks
