VSI Crusher
VSI series impact crusher adopt the latest internation technology, with high stable and high capacity production. This series crusher has three function: crushing, making sand and shaping, widely used in the sand making plant.
TVIS Vertical Shaft Impact Crusher is fine & extra fine crushing equipment to use one of most advanced technology to reach high level, canhandle the high abrasive materials to produce the stones in excellent shapes. It is the optimal equipment for high-standard sand gravel shaping and sand making.
ADVANTAGES VSI CRUSHER HAS MIN. WEAR AND MAX. PROFITS
- The crushing cavity internal items can be changed or repaired easily and fast because of adopting hydraulic device.
- With the unique feeding structure it is convenient to realize the ‘rock on rock” and “rock on ore” can crush and shaping stones.
- Dustproof sealing system completely avoid the external dust into the lubricating parts.
- High quality materials and advanced technology improve the equipment quality and performance.
- The best design of crushing cavity prolong the service time of wearing parts and reduce the cost.
- Feeding pipe of high abrasive alloy material has a long service life
- Feeding distributor are made of high chromium iron wear resistant material high manganese steel plate
- Enclosed rotor designs provide reliable performance and low maintenance.
- Forged hardened and tempered chrome molybdenum steel, large diameters to suit heavy duty application.
- Vertical bearing are produced by the largest manufacturer nationwide and they can support the upper part effectively.
Working Principle Of VSI Sand Maker
The material enters the sand making machine from the feeding port, and the rocks are divided into two parts through the feeder, and one is transferred into the high-speed rotating impeller from the middle of the distributor, and is rapidly accelerated in the impeller, and then ejected from the three uniformly distributed flow channels of the impeller at a speed of 60-70 m/sec.
It is impacted and crushed with the materials falling from the periphery of the distributor, and then impacted together on the material lining of the vortex cavity, rebounded by the material lining, and impacted obliquely upward.
Such a material is subjected to two or even multiple impact, friction and crushing in the vortex chamber. The crushed material is discharged from the lower outlet. During the whole crushing process, the materials are crushed and broken by themselves, which reduces the angular pollution and prolongs the mechanical wear time.
