The VSI sand making machine adopts a vertical shaft impact crushing structure. Materials are fed into the machine from the top feeding hopper and evenly distributed by the internal distributor. Part of the materials enters the high-speed rotating rotor, where they are rapidly accelerated under strong centrifugal force and ejected from the rotor channels at a high speed.

These high-speed materials collide violently with the cascading materials or the impact liner inside the crushing chamber, realizing stone-on-stone or stone-on-iron crushing. Under repeated impact, friction, and grinding, large materials are crushed into fine particles. At the same time, the eddy current inside the cavity continuously shapes the materials, effectively reducing needle and flake content and forming uniform cubic sand particles.

Finally, the qualified finished sand is discharged from the bottom discharge port, while unqualified materials continue to circulate and crush until they meet the size requirement. The whole process features high efficiency, low wear, and stable finished product quality.
