Superior Industries introduced a brand-new conveyor drum pulley at ConExpo-Con/Agg 2020.

The Prime mine-duty pulley is a drum style that’s manufactured in diameters from 4 in. to 30 in. and face widths of 12 in. to 78 in. It’s designed and built with a solid steel end disc, eliminating welding at the hub of the pulley.

Applications for the new pulley include aggregate and mine-duty conveyors using fabric belts that start and stop under full loads frequently.

“Our Prime mine-duty pulley has many of the same design characteristics of Mine Duty 2.0 and Super Duty drum pulleys, but its optimized design yields a lower weight,” says Alan Schmidgall, a vice president at Superior. “That means we can offer a more economically-friendly option and include many of the features our customers said they require.”

The Prime pulley is one of four standard, pre-engineered conveyor pulley models available from Superior. Other designs include CEMA, Mine Duty 2.0 and Super Duty. Superior also offers custom-engineered pulleys from its Core Systems design team.

In addition to the Prime mine-duty pulley, Superior introduced new idler seals, its portable Spirit wash plant, the Sentry horizontal shaft impactor and more at ConExpo-Con/Agg 2020.
