CRUSHING SCREENING

Unlike other types of impact crushers, vertical shaft impact crushers (VSI) are designed with a unique rock-on-rock crushing principle, which significantly reduces the wear costs while offering superior cubical shape for the best quality fine aggregate produc-tion. VSI crushers are usually used in the final stages of the crushing process to shape

5 Aggregate Production - IN.gov

IMPACT CRUSHING Impact crushers may be used as primary, secondary, or tertiary crushers. Despite having a somewhat higher operating cost than other crushers, they tend to produce a more uniform particle shape. Impact crushers usually will benefit the aggregate better than compression crushers, and they may generate more fines.
