VSI high efficiency sand making machine

Working principle

Material falls into the VSI high-efficiency sand making machine's feed hopper, enters the high-speed rotating impeller through the center feed hole, and is rapidly accelerated within the impeller, reaching accelerations up to several times the acceleration of gravity. It is then ejected from the impeller at high speed, first colliding with the material that has rebounded and is now in free fall. This material then strikes the material lining (rock on rock) or the impact block (rock on iron), where it is rebounded upward and impacts the top of the vortex chamber. There, it changes direction, deflecting downward and colliding with material ejected from the impeller flow channel, forming a continuous material curtain. In this way, a piece of material undergoes two or more collisions, friction, and grinding within the vortex crushing chamber. The crushed material is discharged through the lower discharge port.
