A Vertical Shaft Impact Crusher, commonly known as a VSI Crusher or Sand Making Machine, is a tertiary crusher that utilizes high-speed rotors and anvils to crush materials through impact. As the name suggests, the central shaft is mounted vertically. Material is fed into the center of the rotor, which accelerates it and throws it against a stationary anvil ring or a crushing chamber filled with other rocks (rock-on-rock principle).
This unique crushing action is highly efficient for size reduction and, most importantly, for shaping particles into a premium, cubicle product ideal for use as artificial sand or aggregate.
Our VSI crushers are engineered for maximum performance and durability. Key features include:
Hydraulic Lid Opener: Allows for easy and safe access to the crushing chamber for maintenance and inspection.
Versatile Rotor & Anvil Designs: We offer various rotor types (open shoe table, enclosed rotor) and anvil configurations to optimize for different applications (shaping or grinding).
Robust Construction: Built with high-quality wear-resistant materials to withstand abrasive materials and extend service life.
Precise Control Systems: Advanced control systems allow for real-time adjustment of rotor speed and feed rate, ensuring optimal product gradation.
Low Noise and Vibration: Designed for smoother operation, reducing environmental impact.
VSI crushers are incredibly versatile and can process a wide range of hard, abrasive, and brittle materials, including:
Granite, Basalt, and Other Hard Rocks: Ideal for producing high-quality concrete sand and asphalt sand.
Limestone: Effectively crushes limestone into fine aggregates for construction.
Iron Ore and Other Metallic Ores: Used in the beneficiation process.
Bauxite, Quartzite, and Abrasive Materials: Their robust design handles highly abrasive materials.
Industrial Minerals: Perfect for processing minerals like corundum, glass raw materials, etc.
Recycled Materials: Such as concrete, bricks, and other construction waste.
Choosing our VSI crushers brings numerous benefits to your operation:
Superior Product Shape: Produces perfectly shaped, cubicle end products that enhance the strength of concrete and asphalt.
High Crushing Efficiency: Achieves a higher size reduction ratio compared to many other crusher types.
Cubical Product Output: The impact crushing action naturally creates a cubical product, reducing the need for additional shaping.
Low Operating Costs: Simple design and easy wear parts replacement lead to reduced downtime and maintenance costs.
Multi-Functionality: Can be used for fine crushing, grinding, and sand making all in one machine.
We understand that every project has unique requirements. That’s why we provide a comprehensive selection of VSI crusher models with different capacities, rotor speeds, and configurations. Whether you need a compact model for a small quarry or a high-capacity machine for a large-scale mining operation, we have the perfect solution for you. Our expert team can help you select the ideal model to maximize your productivity and return on investment.
The working principle is straightforward yet highly effective:
Feed: Material is fed into the crusher through the center feed tube.
Acceleration: The material falls into the high-speed rotor, which imparts tremendous kinetic energy, accelerating the material outward.
Impact: The accelerated material is thrown against the stationary anvils or the rock lining in the crushing chamber. The resulting impact fractures the material.
Classification: Sized material exits through the discharge opening, while larger particles are recirculated for further crushing.
