All You Need to Know About: Vertical Shaft Impactor (VSI) Primers
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. Normally less than 5inch material is desired, but very large VSIs can handle up to 12inch feed.
