VSI vertical shaft sand making machine is commonly known as impact crusher or aggregate shaping machine. VSI sand making machine is the fourth-generation high-performance sand making machine developed by GBM on the basis of introducing advanced German sand making machine technology and combining with the domestic mining industry conditions. Based on the VSI sand making machine, SBM has successively launched the upgraded VSI5X sand making machine and VSI6X sand making machine.
Product features: lower maintenance cost, longer service life of wearing parts, faster adjustment
Input size: 0-50mm
Capacity: 60-520TPH
Material: granite, quartz, basalt, cobblestone, limestone, dolomite, etc.
The core components use advanced technology and high-quality raw materials, which reduces the failure rate of the VSI sand making machine. The unique damping design effectively reduces the noise of the VSI sand making machine when it is working. The special air circulation system is adopted, which greatly reduces the exhaust air volume and dust emission, and is green and environmentally friendly.
The maximum throughput capacity can reach 520 tons per hour. Compared with traditional equipment, the output of VSI sand making machine is increased by 30% under the same power. In addition, the finished aggregate has excellent cubic shape, reasonable particle size and adjustable fineness modulus, which is especially suitable for artificial sand making and aggregate shaping.
VSI sand making machines are lightweight and can be installed in a variety of ways. Its operation is simple and easy. Once the specific purpose of use is determined, the user only needs to make a little adjustment to give full play to the advantages of the sand making machine. The crusher is equipped with a hydraulic opening device, which facilitates the inspection and replacement of parts in the crushing cavity, saving a lot of time and manpower.
Working Principle
VSI vertical shaft impact crusher (also known as “sand making machine“) has two feeding methods – “center feeding” and “middle feeding”. For the former “center feed” mode, the material in the feed hopper first enters the high-speed spinning rotor through the center hole. In the rotor, the material is sufficiently accelerated and thrown outwards from the launch port, colliding with the material that falls freely after a partial rebound. Next, the material hits the surrounding vortex material lining (or impact block) within the vortex chamber together. In the crushing chamber, the material is first bounced to the top of the crushing chamber, and then changes direction and moves downward, forming a material curtain with the material discharged from the impeller runner. Finally, the finished product is discharged from the bottom outlet. For the latter method, “center side feeding”, first, the material in the feeding hopper passes through a circular hole. The material is then divided into two parts by the distribution tray. Part of the material enters the high-speed rotating impeller, and another part of the material falls from all sides of the tray. The material in the impeller will be rapidly accelerated and thrown outward at high speed, colliding with the material falling from all sides of the tray. Next, all of the material hits the surrounding vortex material lining (or impact block) in the vortex chamber together. In the crushing chamber, the material is first bounced to the top of the crushing chamber, and then changes direction and moves downward, forming a material curtain with the material discharged from the impeller runner. Finally, the finished product is discharged from the bottom outlet.
