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. In Vertical Shaft Impactors material to be crushed hit the other similar covering materials at very high velocity, simultaneously the same crushed particles come in collision with another particles frequently. The feed particles again acquire the velocity with he high impact of the kinetic energy of each other. The particles crack and crush under their mutual hit and force. Vertical Shaft Impact crusher(VSI Sand Making Machine) gives perfect shape of final product. With the help of VSI crusher fine and course material production becomes easy and convenient . The output size in fine or coarse aggregates can be controlled by adjusting velocity of the input material and the distance between the end of the rotor and the impact point. The final output is cubicle in shape. VSI type of crusher is appropriate for materials with high abrasive property and silica content.
