VSI Crusher

SBM VSI crusher is short for Vertical Shaft Impact crusher,which also named VSI sand making machine.The VSI crusher is widely used to make artificial sand.It adopt high quality roller bearing like Sweden SKF and America TIMKEN, which ensure the smooth running of main unit and wven can be operated 720 hours continuously.VSI crusher uses two special crushing method rock on rock and stone on rock crushing method, which ensure the better crushing efficiency of machine.
SBM VSI crusher is designs for three styles of crushing chamber,which offer a maximum flexibility and maximum application versatility.What’s more,VSI vertical shaft impact crusher is also a high-grade shaping machine which helps to ensure the cubic shape of the final product.It has replaced hammer crusher, roller crusher, roller ball mill and become the mainstream equipment in sand-making business.

Application of VSI Crusher

SBM VSI crusher used in various metallic and nonmetallic ores, cement, corhart, abrasive material, glass, construction material, machine-made sand, metallurgy, etc. It is also applicable to crush various stones with different hardness in medium and fine crushing area, such as iron ore, non ferrous metal, emery, bauxite, quartz sand, basalt, etc.SBM VSI crusher is the first choice for tertiary, quaternary crushing of medium hard and super hard material in the artificial sand making.

Distinctive feature of VSI Crusher

  1. Large capacity and high output of 50-500 t/h. The operation is simple, easy to maintain.
  2. A variety of crushing cavity can be mutual transformation,so as to realize multi-usage.
  3. Hydraulic jack device is convenient, save time and energy to maintenance.
  4. Grain shape products, cosmetic effect increased by 30%.
  5. Thin oil lubrication, the main shaft bearing keep constant temperature, prolong maintenance cycle and service life.
  6. Unique air circulation system,working noise is small, reducing the dust and no pollution.
  7. Influence of moisture content is very small and the water content can reach 8%.

Working principle of VSI Crusher

Two feeding ways controlled by the material-dividing plate.

Center Feeding

Raw material falls down into feeding hopper, and then enters impellor through central entrance hole. It is accelerated in high-speed impellor, then is thrown out at speed of 60-75m/s. It is crushed when hitting impact plate. Final products come downwards through the outlet. This feeding way is mainly for sand-making.

Ring Feeding

Raw material falls down into feeding hopper, then through ring, it is divided into two parts by material-dividing plate. Some enter into impellor through the center of material-dividing plate. Some others fall down from outside of material-dividing plate. Material, which is thrown out by impellor at speed of 60-75m/s, hits material coming down from outside of material-dividing plate. In this way, material is crushed. This feeding way is mainly for cubic shaping.
