VSIA7 Series Sand Making Machine

VSI sand making machine uses advanced selective crushing and cleavage crushing principles to directly apply sufficient kinetic energy to the material, and converts the kinetic energy into the crushing energy required to overcome the material through impact to crush it. The material is basically broken along its natural texture surface and cleavage surface, with good particle shape and low self-consumption. Full center feeding: the material falls into the feed hopper and enters the high-speed rotating impeller through the center feed hole. It is rapidly accelerated in the impeller, and its acceleration can reach dozens of times the acceleration of gravity. Then it is ejected from the impeller at high speed, first collides with another part of the material that falls freely after rebounding, and then impacts the material lining (stone hitting stone) or the impact block (stone hitting iron) together, and is rebounded and impacted obliquely upward to the top of the vortex cavity, and then changes its movement direction, deflects and moves downward, and collides with the material emitted from the impeller flow channel to form a continuous material curtain. In this way, a piece of material is subjected to two or more impacts, friction and grinding and crushing in the vortex crushing cavity. The crushed material is discharged from the lower discharge port.
