Vertical Shaft Impactor

The vertical shaft impact crusher is a rock crushing equipment known for its stable and reliable operation, ease of maintenance, and high sand-making efficiency.

Vertical Shaft Impactor, also known as a sand-making machine, is suitable for medium and fine crushing of various hard and brittle materials. It has the advantages of low unit energy consumption, low noise, and high processing capacity. Particularly well-suited for shaping stone and producing manufactured sand, it can be widely used in industries such as hydropower, highways, construction, cement, and metal mining for fine crushing operations.


Vertical Shaft Impactor is an impact crusher that operates on the principle of utilizing centrifugal force to accelerate particles. In VSI crushers, a high-speed rotor with wear-resistant tips or anvils throws material into the crushing chamber, and the rapidly rotating rotor generates centrifugal force, accelerating the material outward. This action causes particles to collide with the lining of the crushing chamber, reducing their size through impact.


Vertical Shaft Impactor can crush 5-200 tons of stone into sand per hour. If you are interested in machines with higher crushing capacity, please contact us for support!

1.What is vertical shaft impactor?

The Vertical Shaft Impactor (VSI), also known as a sand-making machine, is a highly efficient crusher suitable for medium and fine crushing of various hard and brittle materials. It features low energy consumption, minimal noise, and high processing capacity, making it particularly suitable for tasks such as reshaping stones and producing artificial sand. Its versatility extends to applications in hydropower, road construction, cement, and metal mining industries. The VSI operates on the principle of accelerating particles using centrifugal force, impacting and reducing their size through collisions in the crushing chamber. With a capacity of 5-200 tons of material per hour, the VSI is a powerful machine for sand production. Contact us for further information on machines with higher crushing capacities!

2. What is the use for VSI crusher?

The VSI crusher, or Vertical Shaft Impactor, is primarily used for medium and fine crushing of hard and brittle materials. Its main applications include reshaping stones and producing artificial sand. The VSI crusher is particularly employed in industries such as hydropower, road construction, cement, and metal mining. Its ability to efficiently process various materials, along with its low energy consumption and high processing capacity, makes it a versatile and valuable tool in these applications.

3.What are the advantages of vertical shafts?

The advantages of vertical shafts in the context of a Vertical Shaft Impactor (VSI) crusher include:

Efficient Crushing: Vertical shafts in a VSI crusher allow for efficient crushing of materials, providing a high reduction ratio and producing finely crushed particles.

Low Energy Consumption: VSI crushers often have lower energy consumption compared to other crushers, making them more energy-efficient in the crushing process.

High Processing Capacity: The design of the vertical shaft in a VSI crusher allows for a high processing capacity, enabling the crusher to handle large quantities of material effectively.

Versatility: VSI crushers are versatile and can be used for various applications, including reshaping stones and producing artificial sand. They can handle different types of hard and brittle materials.

Uniform Particle Size: VSI crushers tend to produce particles with a consistent size distribution, which is beneficial for certain applications, such as in the production of high-quality aggregates for construction.

Reduced Maintenance: The structure of the vertical shaft and the overall design of VSI crushers often contribute to easier maintenance, reducing downtime and improving the longevity of the equipment.


Noise Reduction: VSI crushers are known for their relatively low noise levels during operation, contributing to a more comfortable working environment.

What is the difference between VSI crusher and cone crusher?

Vertical Shaft Impactor (VSI) crushers and cone crushers are both types of crushers used in the field of crushing, but they have distinct differences in terms of their working principles, applications, and characteristics. Here are some key differences:

Working Principle:

VSI Crusher: Operates on the principle of stone-to-stone crushing. The material is accelerated by centrifugal force in a rotor against the stationary anvils or curtains, resulting in rock-on-rock crushing.

Cone Crusher: Operates on the principle of compression crushing. Material is fed into the crushing chamber, and as it progresses downward, it is crushed between the mantle and the bowl liner.

Particle Size and Shape:

VSI Crusher: Often produces more cubical and fine particles, suitable for producing high-quality artificial sand and shaped aggregates.

Cone Crusher: Typically produces coarser particles with a more elongated shape.


VSI Crusher: Commonly used for shaping and producing artificial sand. Suitable for tertiary and quaternary crushing stages.

Cone Crusher: Widely used for secondary and tertiary crushing in various applications, including mining, aggregate, and construction.

Material Hardness:

VSI Crusher: Generally more effective for crushing harder and abrasive materials.

Cone Crusher: Suitable for a wide range of materials, including softer rocks and minerals.

Maintenance and Operating Cost:

VSI Crusher: Often requires less maintenance and has lower operating costs compared to cone crushers.

Cone Crusher: Maintenance requirements can be higher, and operating costs may vary depending on the application.


VSI Crusher: Versatile for various applications, especially in the production of manufactured sand.

Cone Crusher: Versatile and widely used in different industries, but may not be as specialized for certain applications as VSI crushers.

Ultimately, the choice between a VSI crusher and a cone crusher depends on the specific requirements of the application, the type of material being crushed, and the desired end product.

4. What is VSI sand?

VSI sand, crafted by the Vertical Shaft Impactor (VSI) crusher, represents a premium-grade, finely crushed sand characterized by its uniformity, superior shape, and cubical particles. This product is ideal for diverse construction uses, providing optimal performance and contributing to environmentally sustainable building practices.

5. What is a Vertical Shaft Impactor (VSI)?

A VSI, or Vertical Shaft Impactor, is a type of impact crusher used for crushing various hard and brittle materials. It operates on the principle of accelerating particles with centrifugal force to break them down into smaller sizes.

6. What distinguishes VSI sand from natural sand?

VSI sand, produced by Vertical Shaft Impactors, is known for its consistent particle size, superior shape, and cubical characteristics, providing advantages over naturally occurring sand.

7. What are the key advantages of VSI sand in construction?

VSI sand offers benefits such as uniformity, optimal shape, and cubical particles, making it an ideal choice for construction applications that demand high-quality sand with enhanced performance.

8. In which industries is the Vertical Shaft Impactor commonly used?

The VSI is widely used in industries like water and electricity, road construction, building, cement, and metal mining, where fine and efficient crushing of hard and brittle materials is required.

9. How does a Vertical Shaft Impactor work?

The VSI crusher operates by using a high-speed rotor with wear-resistant tips to throw materials into a crushing chamber. Centrifugal force generated by the rotor accelerates the particles, causing them to collide with the chamber’s lining and break down through impact.

10.What hourly production capacity can be achieved with a Vertical Shaft Impactor?

Vertical Shaft Impactors are capable of crushing 5-200 tons of material per hour, making them suitable for various production requirements.
