Usually positioned after your primary or secondary crusher, Vertical Shaft Impactors (VSI) consistently produce cube-shaped material. The shape and size of the final product is a spec required by most modern asphalt contractors including “Superpave.”
During production at the quarry, feed material contacts the VSI’s rotor which rapidly launches it against stationary anvils. This collision causes the rock to break along its natural fault lines.
Compared to compression crushers like jaws and cones, impactors accept larger feed sizes, process higher tonnage and allow customization of particle shape and size.
