Vertical shaft impact (VSI) crushers are generally used in the third crushing stage. Compared to other tertiary crushers, the VSI crusher consumes less energy and produces a better-shaped grit with a finerproduct size.1,2 Concrete made of manufactured sand has better physical properties than natural sand concrete.
