Superior Patents Recirculating Conveyor On Sentry HSI Plant

May 29, 2025 - one year ago

Superior Industries has been awarded patent protection for a key feature on its Portable Sentry Horizontal Shaft Impactor (HSI) Closed Circuit Plant.

The newly patented recirculating conveyor delivers returning material back to the HSI with a centered, uniform feed. This centralized approach ensures full utilization of the crusher’s blow bars, significantly improving wear life and reducing cost per ton in recycled concrete, reclaimed asphalt, and other crushing and screening applications.

“Uneven wear is one of the hidden killers of cost efficiency,” says Devon McKinney, Superior’s product manager for portable plants. “With this design, our engineers found a way to take care of the crusher and a producer’s bottom line at the same time.”

By contrast, other HSI closed-circuit plants commonly introduce recirculated material from one side of the crusher, causing blow bars to wear unevenly and increasing replacement frequency.

In addition to the hydraulically-positioned recirculating conveyor, the Portable Sentry HSI Plant also includes these features:

Intrepid Vibrating Grizzly Feeder equipped with interchangeable grizzly cassettes (bars, fingers or punch plates) to accommodate multiple applications.
2-deck Anthem Inclined Screen for sorting up to three sizes of material and includes extra clearance between decks, which eases human access for maintenance.
Universally designed cross conveyors are fully interchangeable, allowing producers to rotate them as needed and minimize inventory requirements.

The new recirculating conveyor patent reinforces Superior’s commitment to practical innovation focused on uptime, safety, and long-term cost savings.
