Vertical Shaft Impactors (VSI)

Vertical Shaft Impactors (VSI)

Vertical Shaft Impactors (VSI) are advanced technology equipment that work on the principle of crushing material by impacting it through a high-speed rotating rotor. The system is based on the material being fed into the rotor from the upper feeding opening, being accelerated at high speed to gain kinetic energy, and then being fragmented by striking against a stone bed or specially armored surfaces in the crushing chamber. Thanks to this impact effect, the material acquires a cubic form and product quality is improved. The crushed material is discharged in a controlled manner from the lower outlet, ensuring process continuity and optimizing production efficiency.
