What Is A Vertical Shaft Impactor (VSI) Primer?
The VSI is typically used after a primary or secondary crusher. This makes a VSI ideal for making sand and for making coarse and medium aggregates for concrete/asphalt production. Feed size and characteristics will affect the application of a VSI. The feed size is limited by the opening in the center of the rotor.

Advanced comminution modelling: Part 1 – Crushers
The energy dissipation is split with 80% in rock-crusher collision (mechanisms 1, 2 and part of 4) and 20% in rock-rock collisions which is far from negligible (mechanism 3 and part of 4). This demonstrates that re-breakage from rock-rock collisions is an important minority component of the breakage process in the VSI.
