Vertical Shaft Impact Crusher|VSI Crusher

Vertical shaft impact crusher is also called vsi crusher. This crushing machine is a kind of highly efficient rock crushing plant at domestic and international advanced level researched and developed by Shanghai Shibang Machinery Co., Ltd. by introducing the famous crusher principle and technology of “stone against stone" from America Barmac Company in accordance with the actual conditions of sand production at home.

VSI Crusher



VSI crusher is widely used for medium and fine crushing (sand making) for various hard and brittle materials such as rocks, grinding materials, refractory materials, cement clinker, quartz, iron ore and concrete aggregate, etc. It is especially appropriate for sandstone for architecture and road construction.


Working principle:


load through boot into the vsi crusher. The materials are divided into two parts by the distributor. One enters rapidly rotating impeller through middle of the distributor. Then the impeller speeds up immediately with acceleration hundreds of times higher than acceleration of gravity. The materials are thrown out through 3 evenly distributed flow passages from the impeller at a speed of 60-70m/s to be crushed together with the part of materials left around the distributor, and then impacted to the material lining in vortex cavity branch.

After rebound by the lining, the materials are impacted transversely upward to top of the vortex cavity, and then move downward. Materials transmitted from flow passages of impeller form a continuous material curtain. A piece of material undergoes random impact, friction and grinding for at least twice in the vortex crushing cavity.

The crushed materials are discharged through discharge slot on the lower part. The vsi crusher forms closed circuit with circulative screening system. Generally, the materials will become less than 20 meshes after circulation for 3 times. During the whole crushing process, the materials impact and crush with each other. Not contacting directly with metallic components, the materials are crushed by impact and friction with the lining, so as to reduce corner pollution and extend the time of mechanical wear. Dust pollution is eliminated by ingenious self-circulating air in the vortex cavity.
