Working Principle Flow
1. Feeding Stage
Materials enter the crushing chamber through the feeding hopper.
↓
2. Acceleration Stage
A high-speed rotating impeller accelerates the materials.
↓
3. Ejection Stage
Under centrifugal force, materials are ejected at high speed.
↓
4. Crushing Stage
Crushing occurs through three mechanisms:
Material-to-material impact
Material-to-liner impact
Vortex collision inside the chamber
↓
5. Discharge Stage
Crushed materials are discharged from the lower outlet.
↓
6. Continuous Cycle
The system forms a continuous crushing and shaping circulation.

FAQ
Q: What is a VSI crusher used for?
A: It is applied in manufactured sand production and aggregate shaping for mining, construction, and infrastructure applications.
Q: What is the difference between a VSI and a cone crusher?
A: The VSI crusher applies high-speed impact crushing for particle shaping. A cone crusher applies compression crushing for secondary or tertiary reduction.
Q: What materials can it process?
A: It processes medium-hard to hard rock materials, including granite, basalt, limestone, quartz, and similar aggregates.
Q: Is maintenance complex?
A: Maintenance is based on a modular wear parts system with replaceable rotor components and chamber liners.
Q: Can the output size be adjusted?
A: Yes. Output gradation is controlled by rotor speed, feed mode (central or cascade), and crushing chamber configuration.
