Vertical Shaft Impact crusher

also is named

sand making machine

. Nowadays, VSI crusher has replace hammer crusher, roller crusher, roller ball mill, etc. and become the mainstream equipment in sand making business.

The Vertical Shaft Impact crusher is widely used in many materials like rock, abrasives, refractories, cement clinker, quartz stone, iron ore, and concrete aggregate and so on, and more suit for construction sand, gravel roads to use. According to the customer for many years of production experience, we can prove that my company's Sand making machine (VSI Crusher) has features of stable of performance ,reasonable structure, high quality, far ahead of other companies of similar products.

After materials are fed into the hopper, they are, through a central feeding hole, thrown to the impellers, which are rotating at a high speed. Then, the material are accelerated and thrown out of impeller area. These parts of materials, first, impact on the other part of materials, which are falling down, and then, they together strike on the material layers or on impact blocks. Due to rebound, they will back to top of crushing cavity and again be shot back to stick on another part of materials which are shot from the impeller flow and form a continuous material curtain. The final products will be discharged from the discharge open at the bottom.

• VSI crusher incorporates three crushing styles; its feeding style incorporates material on material, materials on iron and falling at sides. Customers can adjust the crusher machine according to their own demand.
• VSI crusher realizes multiple functions in one machine, which is a big breakthrough in sand making field.
• Our VSI crusher is designed by reputed German expert and every index of VSI crusher is in world’s leading standard.
• The impact crusher can be operated 720 hours continuously.
• Better quality and high efficiency: better design of the impellers reduces the resistance of materials; high lightens passing through quantity of materials and crushing ratio, so the efficiency is raised by 30%-60% compared to traditional crushing machines.
• Hydraulic system allows automatic uncovering, which reduces labor intense and makes maintenance easier.
• The mainframe adopts new techniques, which strengthens the crusher machine structure and tenacity, and ensures stable performance.
• The quality of the crusher machines is lift to a higher level.
• VSI crusher employs world advanced light oil anti-leakage device. This saves the trouble of changing oil seal.
