=12px[color=#000000]The center feeding of the
sand making machine (impact crusher) is accompanied by the annular fall feeding: the material falls into the sand making machine (impact crusher) feeding hopper and falls through the annular hole. The material is divided into two parts by the feed plate. One part enters the high-speed rotating wheel through the feed plate and the other part falls around the feed plate. Into the sling wheel material, within the sling wheel is accelerated rapidly, its acceleration can be up to several times the acceleration of gravity, then the shot from the left wheel, first by the distributor with free fall around the other part of the material impact crushing, then hit with eddy current eddy current on the lining cavity, be lining material rebound, oblique upward shocks to the top of the vortex chamber, and change the direction of movement, deflecting downward movement, and the material impact emitted from the impeller passage to form a continuous material. In this way, a piece of material receives two or more chances of impact, friction and grinding and crushing in the eddy current crushing chamber. The crushed material is discharged from the lower discharge port to the sand making machine (impact crusher).[/color] =12px[color=#000000]Working principle of impact crusher:[/color] =12px[color=#000000]Counterattack crusher feed: all material into the impact crusher feed hopper, center of the feed opening into the high speed rotating sling wheel, within the sling wheel is accelerated rapidly, its acceleration can be up to several times the acceleration of gravity, then the shot from the left wheel, and rebound after the first free fall impact the other part of the material, then hit with lining material (stone hit stone) or counter piece of stone (iron), bounced inclined upward shocks to the top of the vortex chamber, and change the direction of movement, deflecting downward movement, and the material impact emitted from the impeller passage to form a continuous material curtain.
