Vertical Shaft Impactor
Crush the hardest and biggest stones
What is a VSI Crusher?
A Horizontal Shaft Impact (HSI) crusher are essential in the world of stone crushing for producing high-quality aggregate, cubical-shaped products in the construction and mining industries. The process involves a high-speed rotor with wear-resistant tips that accelerates the material through centrifugal force. As rocks collide against each other, they break into smaller particles, creating a more cubical product compared to traditional crushers. This unique crushing action makes VSI Crushers highly effective in various applications, from construction to mining.

VSI Crushers Assembly Process
-
Frame Assembly: The foundation of a VSI crusher is its robust frame. Skilled technicians meticulously assemble the frame, ensuring precision and durability. The frame serves as the backbone, supporting the critical components that follow.
-
Rotor Construction: The heart of every VSI crusher is its rotor. Crafted from high-quality materials and precisely balanced, the rotor undergoes rigorous assembly. Technicians attach the wear-resistant tips, ensuring optimal impact velocity and extended operational life.
-
Chamber Configuration: The crushing chamber is carefully configured to maximize efficiency and product quality. Skilled workers assemble the chamber components, creating the perfect environment for the high-speed rotor to deliver effective crushing.
-
Drive System Integration: The powerful drive system is integrated with precision, connecting the motor to the rotor. This step ensures the seamless transfer of power, allowing the crusher to operate at the required speed for optimal performance.
-
Finishing Touches and Quality Checks: Before a VSI crusher leaves the assembly line, it undergoes meticulous quality checks. Every detail is inspected, from the alignment of components to the functionality of safety features. Technicians add the finishing touches, ensuring each crusher meets the highest industry standards.
Types of VSI Crushers:
Open Rotor and Closed Rotor VSI Crushers:
- Open Rotor: Allows larger feed sizes and is suitable for crushing softer materials.
- Closed Rotor: Ideal for tougher, more abrasive materials and offers better control over the product shape.
Rock-on-Rock and Rock-on-Steel VSI Crushers:
- Rock-on-Rock: Crushing occurs between the rocks themselves, delivering superior shaping of the final product.
- Rock-on-Steel: Utilizes a crushing chamber lined with steel components, suitable for high-abrasion applications.
Static and Dynamic VSI Crushers:
- Static: Designed for stationary installations, providing a cost-effective solution for specific production needs.
- Dynamic: Mounted on mobile platforms, offering flexibility and adaptability for on-the-go crushing requirements.
