Superior gain patent for recirculating conveyor on Sentry HSI plant
Centralized feed design maximizes blow bar life and reduces cost per tonne for producers
SUPERIOR Industries Inc. have been awarded patent protection for a key feature on their portable Sentry horizontal-shaft impactor (HSI) closed-circuit plant that reinforces the company’s commitment to practical innovation focused on uptime, safety, and long-term cost savings.
The newly patented recirculating conveyor delivers returning material back to the HSI with a centred, uniform feed. This centralized approach ensures full utilization 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.
‘Uneven wear is one of the hidden killers of cost efficiency,’ said 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.’
In 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:
An Intrepid vibrating grizzly feeder equipped with interchangeable grizzly cassettes (bars, fingers or punch plates) to accommodate multiple applications
A two-deck Anthem inclined screen for sorting up to three sizes of material (includes extra clearance between decks to ease human access for maintenance)
Universally designed cross-conveyors that are fully interchangeable, allowing producers to rotate them as needed to minimize inventory requirements.
