Crushing Equipment :VSI (vertical shaft impact) crusher
The newly- developed VSI (vertical shaft impact) crusher is a crusher and shaper. Changing feeding methods and core structure of the crushing cavity, it can be used as a crusher or a shaper. Thus, customers do not need to expand investment, they have a crusher and a shaper at a time.
VSI crushers are widely applied in expressway and railway building, hydropower station construction, bridge and tunnel building, concrete batching plant, etc for crushing and gravel shaping.They are highly recommended when it comes to the shaping of gravels used in concrete aggregates, whose concrete strength is above C 60 or which required to be freezeproof and leakproof. In the fine crushing section, VSI is the substitute of impact crusher, and it is much better in terms of main performance indexes.

Crushing Equipment : VSI crusher Working Principle
Materials fall into the hopper and then through the feeding opening in the center enter the high speed rotor which will throw out the materials with high speed. Materials firstly strike those materials that are free falling down. Then, materials strike the materials-liner in the vortex or the impact liner and are rebounded to the top of crushing cavoty and then fall down. After that, the falling materials with materials shot from the impeller form a continuous materials curtain. Ultimately, crushed materials will be charged from the discharging opening.
