load through boot into the PCL 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.
