Sentry™ Horizontal Shaft Impactor (HSI)

Using a high speed impacting force, horizontal shaft impactors, like the patented Sentry HSI, encourage stones to break along their natural cleavage lines. This generates cubically-shaped material, which is desirable for many of today’s applications.

Superior’s Sentry HSI is designed with a fully-fabricated open-style rotor, which produces high inertia energy for a lower cost of ownership. In addition, proper spacing inside the crusher’s chamber creates more area for processing larger feed sizes. Owners and operators will safely and easily inspect the HSI’s mainframe components via a hydraulically-controlled opening and closing feature.
