Vertical Shaft Impact Crusher, also known as VSI crusher, is a popular type of rock crushing equipment that is used for the purpose of producing sand and gravel for construction. It operates on the principle of high-speed impact and attrition to break rocks into smaller sizes.
The VSI crusher consists of a vertical rotating shaft with a rotor mounted on it. The rotor has several wear-resistant tips or anvils, which are made of materials such as tungsten carbide or hardened steel. As the rotor spins at high speed, the material is fed into the center of the rotor from above and then thrown outwards towards the stationary anvils. This process results in the creation of rock-on-rock collisions and rock-on-iron collisions that break the material down into smaller sizes.
One of the advantages of the VSI crusher is that it can produce a uniform particle shape with a high percentage of fines, making it suitable for applications such as concrete production, asphalt production, and road base material production. Additionally, VSI crushers are * for processing abrasive and hard materials such as granite, basalt, and ores like iron and copper. Another advantage of the VSI crusher is its flexibility in terms of adjusting the product size and shape. The machine can be easily adjusted to produce different sizes of aggregates by changing the rotor speed, the number of anvils, and the feed rate. This makes it possible to produce a wide range of aggregate products with just one machine.
In conclusion, Vertical Shaft Impact Crusher is an essential piece of equipment that is widely used in the mining, construction, and recycling industries. Its ability to produce a uniform particle shape with a high percentage of fines and its flexibility in adjusting the product size and shape make it a versatile and valuable tool for any operation that requires the production of aggregates.
