A Vertical Shaft Impact Crusher (VSI) is a high-efficiency crusher used in crushing and screening plants, particularly for fine material production. These crushers operate by rotating material at high speed and crushing it through impact forces.

VSI crushers are ideal for crushing hard and abrasive materials and producing cubic-shaped aggregates. They are widely used for concrete aggregate, asphalt filling, and sand production.

Technical Features and Advantages of VSI Crushers

High Capacity and Efficiency: Operates at rotor speeds of 1000-3000 RPM, providing high crushing capacity.
Cubic Material Production: Turns irregular and angular stones into cubic-shaped aggregates.
Low Wear Costs: Special alloy rotors and wear-resistant internal linings ensure long-lasting performance.
Multiple Feeding Options: Can work with central feeding or peripheral feeding methods.
Energy Efficiency: Consumes less energy while delivering high performance.
Suitable for Recycling: Effectively processes concrete, asphalt, and construction waste into reusable materials.
Automated Control and Safety: PLC-controlled systems allow remote monitoring and adjustments.

Working Principle of VSI Crushers

The feeding unit directs stone or mineral material into the crusher.
Material enters the rotor and spins at high speed.
The rotor propels the material at high velocity toward the crushing chamber walls.
Material collides with the chamber walls and other rock fragments, breaking apart.
Smaller particles form and are sent to the screening system.
The final crushed material is transported via conveyor belts.

This system produces more homogeneous and high-quality output compared to hammer or impact crushers.
