Working principle of vertical shaft impact crusher

   1. Center Feeding:

   Raw material falls down into feed hopper, then enter into impellor through central entrance hole. It is accelerated in high-speed impellor,  When it hits impact plate, it is crushed. Final products come downwards though outlet.

   2. Ring Feeding:

   Raw material falls down into feed hopper, then through ring, it is divided into two divisions by material-dividing plate. One enters into impellor through the center of material-dividing plate. The other falls down from outside of material-dividing plate. Material, which is thrown out by impellor ,hits material coming down from outside of material-dividing plate. In this way, material is crushed.
