A crushing stone impact plant (also known as an impact crusher plant) is a mobile or stationary crushing system designed to break down rocks and stones using high-speed impact forces. These plants are commonly used in mining, quarrying, and recycling applications to produce aggregates for construction.
Key Components of a Stone Impact Crushing Plant:
1. Primary Feeder – Delivers raw material (e.g., rocks, boulders) into the crusher.
2. Impact Crusher – The core machine that crushes stones using hammers/blow bars striking the material at high speed.
– Common types: Horizontal Shaft Impact Crusher (HSI) & Vertical Shaft Impact Crusher (VSI).
3. Vibrating Screen – Separates crushed material into different sizes (e.g., fine sand, gravel).
4. Conveyor Belts – Transport crushed stone between stages.
5. Control System – Automated or manual controls for adjusting settings.
6. (Optional) Secondary Crusher – Further refines material if needed (e.g., cone crusher).
Advantages of Impact Crushing Plants:
✔ High reduction ratio
✔ Cubical-shaped end product (ideal for concrete/asphalt)
✔ Efficient for medium-hard to hard stones
✔ Can handle abrasive materials
Applications:
- Quarrying & mining
- Recycling (concrete, asphalt demolition waste)
- Road construction aggregates
- Railway ballast production
- Metso Nordberg® NP Series
- Sandvik CI Series
- Terex Pegson / Powerscreen Trakpactor
- Kleemann MR Series
