VSI Crusher

The vertical shaft impact crusher is mainly applied in fine aggregate production line, frac sand making plant, machine-made sand making plant, etc. You can use it to make sand(ston dust) from stones, solid waste, etc.

How is the vertical shaft impact crusher working? As for the former mode "feed at center", materials at the feed hopper firstly pass through the central hole into the high-speed spinning rotor. In the rotor, materials are fully accelerated and thrown outwards from the launching port to collide with a part of materials that freely fall after rebound. Next, materials hit the surrounding vortex material liner (or the impact block) inside the vortex chamber together. In the chamber, materials are bounced to the top of crushing chamber firstly and then change their direction by moving downwards to form a material curtain with materials emitted from the runner of impeller. Finally, finished products are discharged from the bottom discharge opening.
