Sentry® Horizontal
Shaft Impactor (HSI)
PRECISE PRODUCT SHAPE & SIZE
A Horizontal Shaft Impact (HSI) crusher is one of the most popular tools for producing cube-shaped products.
Feed material quickly contacts a series of blow bars spinning rapidly on a rotor. These blow bars (hammers) violently toss the rocks against steel curtains (aprons). Eventually, newly shaped rock exits the opening at the bottom of the HSI.
Compared to compression crushers like jaws and cones, horizontal shaft impactors will accept larger feed sizes, process a higher tonnage and allow excellent control of particle shape and size by simply adjusting the spacing of its internal components.
Superior builds more than a dozen HSI models:
- Maximum feed size up to 31″ (800mm)
- Product size of 10″ – 1″ (254 – 25mm)
- Maximum tonnage rate of 990 STPH (900 MTPH)
