Superior Industries Awarded Patent for Recirculating Conveyor on Sentry HSI Plant | For Construction Pros

Jun 05, 2025

Superior’s patented conveyor design centralizes material feed to extend blow bar life and lower cost per ton in crushing applications.

Superior Industries, a U.S. manufacturer of bulk material processing and handling equipment, has been granted a patent for the recirculating conveyor system used on its Portable Sentry Horizontal Shaft Impactor (HSI) Closed Circuit Plant.

The patented design feeds recirculated material back into the crusher with a centered and consistent flow, helping to evenly distribute wear across the blow bars. This approach is intended to extend the life of wear parts and reduce operating costs in applications such as recycled concrete and reclaimed asphalt.

In conventional HSI closed-circuit setups, recirculated material is typically fed from one side, leading to uneven wear and more frequent maintenance. Superior’s centered feed design addresses this issue by promoting uniform wear patterns.

Additional features of the Portable Sentry HSI Plant include:

The patent supports Superior’s focus on improving operational efficiency through design changes that contribute to uptime and cost management in material processing.
