Superior Industries has secured 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 to the HSI via a centered, uniform feed.
This centralised approach ensures full utilisation of the crusher’s blow bars, significantly improving wear life and reducing cost per tonne in recycled concrete, reclaimed asphalt, and other crushing and screening applications.
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.
Superior Industries product manager for portable plants Devon McKinney said the new patent reinforces Superior’s commitment to practical innovation focused on uptime, safety, and long-term cost savings.
“Uneven wear is one of the hidden killers of cost efficiency,” he said.
“With this design, our engineers found a way to take care of the crusher and a producer’s bottom line at the same time.”
The Portable Sentry HSI Plant also includes these features:
- The Intrepid Vibrating Grizzly Feeder equipped with interchangeable grizzly cassettes (bars, fingers or punch plates) to accommodate multiple applications.
- The two-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 minimise inventory requirements.
