The Sentry horizontal shaft impactor (HSI) uses a high-speed impacting force to break stones along natural cleavage lines, according to the company, producing cubically shaped material.
The Sentry HSI is designed with a fully fabricated open-style rotor, which produces low inertia energy for a lower cost of ownership.
Other design elements include commonly shaped side liners, hydraulically adjusted curtains, mainframe inspection doors, and a replacement upper feed opening. One- or two-piece blow bars manufactured with two or four rotors are equipped with fixed clamping for best performance in hard rock applications.
Fifteen models are available with production capacities ranging from 90 to 990 tons per hour with maximum feed sizes from 15 to 40 inches.
