Types of Crushers Explained: Everything You Need to Know
HSI crushers utilize a horizontal rotor that throws the material on stationary anvils or curtains, which results in the material breaking upon impact. VSI crushers, unlike the traditional crushers, have a vertical rotor which accelerates the material and throws it against a stationary anvil ring or a cloud of material itself.
