What's VSI5X Crusher Working principle?

Feed at center (figure 2): Materials fall into the hopper and then through the central well enter the high speed rotator which will throw out the materials with high speed. Firstly, the materials strike with the materials that are free falling down. Secondly, materials strike the materials-liner in the vortex or the impact liner and are rebounded to the top of crushing cavity and then deflecting fall down. Thirdly, the falling materials with the shoot materials form a continuous materials curtain. Lastly, crushed materials be discharged from the under discharging opening.    

    
Feed both at center and at sides (figure3): The materials fall into the hopper and circle hole and then be dividend into two pats by the distributing plate, One part of materials cross the distributing plate and enter in to the high speed impeller and then is accelerated and throw out from the impeller . The other falls down from the sides of distributor. Firstly, the materials strike with the materials that are free falling down. Secondly, materials strike the materials-liner in the vortex or the impact liner and are rebounded to the top of crushing cavity and then deflecting fall down. Thirdly, the falling materials with the shoot materials form a continuous materials curtain. Lastly, crushed materials be discharged from the under discharging opening.
