shaft stone crusher

A shaft stone crusher typically refers to a type of crushing equipment that uses a rotating shaft or hammer system to break down stones into smaller pieces. Below are the key aspects related to shaft stone crushers:

1. Types of Shaft-Based Stone Crushers
– Hammer Crusher: Uses high-speed rotating hammers attached to a shaft to impact and crush stones against breaker plates.
– Vertical Shaft Impact Crusher (VSI): Uses a high-speed rotor to throw stones against anvils or crushing chambers, producing finely crushed aggregates (ideal for sand and gravel production).
– Horizontal Shaft Impact Crusher (HSI): Similar to VSI but with a horizontal rotor, suitable for softer materials like limestone.

2. Working Principle
– Stones are fed into the crusher’s chamber.
– A rotating shaft with hammers or impellers strikes the stones, breaking them into smaller fragments.
– Crushed material exits through grates or adjustable openings.

3. Applications
– Mining and quarrying (granite, limestone, basalt).
– Construction aggregates (road baseoncrete production).
– Recycling (concrete, asphalt debris).

4. Advantages
– High reduction ratio.
– Adjustable output size.
– Efficient for medium-hard to hard materials.

5. Considerations When Choosing a Shaft Crusher
– Material Hardness: VSI works best for abrasive materials; HSI is better for softer rocks.
– Output Size: Adjustable settings control the final product size.
– Maintenance: Shaft bearings and wear parts require regular inspection.

6. Popular Brands & Models
– Sandvik CV & CI Series (HSI & VSI)
– Metso Barmac® B-Series VSI
– Terex Canica Vertical Shaft Impactors
