2026 PROMAC Sentry HSI Impact SS4355G

2026 PROMAC Sentry HSI Impact SS4355G

Using a high speed impacting force, horizontal shaft impactors, like the patented Sentry HSI Impact Crusher, 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 low 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.

Features may include:

• Open rotor design with high inertia provides lower cost of ownership

• Easily adjust the crusher’s closed side setting (CSS)

• Increase safety during the removal or lifting of blow bars

• Included with all machines, this device will improve safety

• Safely and simply access internal components for inspection.

• Two or four blow bar rotor option with one or two-piece bars manufactured in a robust 4.5” (114mm) minimum manganese or chrome.

• Mix and match these liners to prolong wear life and decrease cost of replacement components.

• Access the crushing chamber at additional locations including top, side and back inspection

• Provides maximum clamping for best performance in hard rock applications.
