A stone impact crusher is a type of mining machinery widely used in the crushing and processing of rocks, ores, and construction aggregates. It utilizes impact force to break materials into smaller sizes, making it ideal for medium-hard to hard materials like limestone, granite, and concrete.
Key Features of Stone Impact Crusher:
1. High Crushing Efficiency – Uses impact energy to crush materials with high reduction ratios.
2. Adjustable Output Size – The final product size can be adjusted by changing rotor speed or adjusting impact plates.
3. Versatile Applications – Suitable for mining, quarrying, recycling (concrete demolition), and construction industries.
4. Durable Construction – Made with high-quality wear-resistant materials (e.g., manganese steel) for long service life.
5. Low Maintenance – Simple structure with fewer wear parts compared to jaw or cone crushers.
Working Principle:
– Material enters the crusher and is struck by high-speed rotating hammers/blow bars on the rotor.
– The material is thrown against impact plates (liners) inside the crushing chamber, breaking into smaller pieces.
– The crushed material exits through adjustable grates or aprons.

Types of Impact Crushers:
1. Horizontal Shaft Impact Crusher (HSI) – Commonly used in aggregate production.
2. Vertical Shaft Impact Crusher (VSI) – Produces finer, more cubical aggregates (used in sand making).
Advantages Over Other Crushers:
– Better grain shape (cubical output).
– Higher reduction ratio tha.jpg)
