What Is a Vertical Shaft Impact Crusher (VSI) and How Does It Work?
In a vertical shaft impact crusher (VSI), material is fed from the top into the centre of the rotor and thrown by the high-speed rotor against an anvil ring or a rock shelf formed by its own material. Rock-on-rock operation reduces wear, while rock-on-metal operation increases the share of fines.
With cubical particle shape and controlled fines generation, the VSI is the key machine for manufactured sand production and aggregate shaping.
Applications
- Manufactured sand (M-sand) production
- Shaping chippings (cubicity)
- Tertiary and quaternary crushing of hard rock
- Crushing glass, slag and industrial minerals
Selection Checklist
- Rotor type (rock shelf or metal anvil) chosen for the material
- Rotor speed determines product fineness
- Feed size and moisture limits respected
- Cascade feed ratio can be used to control fines

Frequently Asked Questions
How is manufactured sand produced with a VSI?
0–20 or 0–30 mm material from the secondary crusher is crushed in the VSI, screens separate 0–4/0–5 mm sand, and fines are controlled by washing or air classification if needed.
How long do VSI rotor tips last?
Life depends on material abrasiveness, rotor speed and feed arrangement; tips should be replaced as a set to keep the rotor balanced.
