Sentry® Horizontal Shaft Impactor (HSI)
Sustainable Material Recycling
Horizontal Shaft Impactors (HSI) are widely used in demolition, aggregate recycling, or operations producing road base material.
That’s because they typically handle a wider range of material and produce less fines than VSI crushers– two features important for concrete and asphalt recycling or crushing glass and bricks.
Superior’s Sentry HSI is a rugged and resilient horizontal impact crusher capable of processing large feed sizes from dirtier conditions.
Clay & Brick Crushing
Convenient Hydraulic functions
Hydraulically-designed components include curtain adjustments and opening/closing of the chamber.
How An HSI Works
Upon entry, 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) causing the material to break. Eventually, newly shaped rock exits the opening at the bottom of the HSI.
