Condition: new, functionality: fully functional, Year of construction: 2025, The VSI (Vertical Shaft Impactor) sand making machine is a type of crusher designed to accelerate the crushing of aggregate and produce cubical-shaped sand. It is widely used in the field of construction, mining, and other similar industries. Here are key features and information about VSI sand making machines: 1. Working Principle: - The VSI sand making machine operates on the principle of stone impacting stone or stone impacting iron. Material is fed into the center of the rotor, which accelerates to high speed to throw the material outward against a wear-resistant lining. 2. Rotor and Crushing Chamber: - The rotor is a crucial part of the VSI machine and is often designed with multiple pockets to facilitate material throwing and crushing. - The crushing chamber is lined with wear-resistant materials to endure the impact and abrasion during the crushing process. 3. Feedstock Control: - The feedstock (material to be crushed) can be controlled using a variable speed control system, allowing for adjustments to achieve the desired particle size. 4. Material Types: - VSI machines are suitable for processing various materials, including hard and abrasive materials such as rocks, ores, and minerals. 5. Cubical Shaping: - One of the significant advantages of VSI machines is their ability to produce cubical-shaped end products, which is desirable for high-quality concrete and asphalt production. Kfsdpfx Aasq Nd U Honsa 6. Adjustable Discharge: - The machine usually has an adjustable discharge opening, allowing for customization of the final product size. 7. Sand Production: - VSI sand making machines are primarily used to produce manufactured sand (M-sand) and crushed sand, which are essential components in the construction industry. 8. Maintenance: - Regular maintenance is required to ensure optimal performance and extend the machine's lifespan. This includes checking wear parts, lubrication, and addressing any issues promptly. 9. Variations: - Different manufacturers may offer variations of VSI machines with unique features or specifications. Common variations include open rotor and closed rotor designs. 10. Environmental Considerations: - VSI sand making machines are generally considered environmentally friendly as they produce less dust and noise compared to traditional crushers. 11. Manufacturers: - Well-known manufacturers produce VSI sand making machines, and it's crucial to choose a reputable supplier with a track record of providing reliable equipment. When considering a VSI sand making machine, factors such as feed size, capacity, and the desired end product specifications should be taken into account. Additionally, check the reputation of the manufacturer, and consider customer reviews and feedback regarding the specific model you are interested in.
