Vertical Shaft Impact crusher (VSI Sand Making Machine) uses a unique rock on rock crushing method employing a high speed rotor with crushing chamber of the equipment. Velocity is applied in Vertical Shaft Impact crushers as the resulting force, to break stone particles. While applying velocity rather than surface force the breaking force to be applied evenly on the surface of the rock.

7. Shape of material-through device is better designed, which improve the utilization ratio.
