Sturtevant Introduces New Whirlwind Mobile Air Classifier

Sturtevant’s new Whirlwind® Mobile Air Classifier is the world’s first and only 100% mobile
classifying plant with integral collapsible conveyors. The Whirlwind® Mobile Air Classifier was built whirlwind-mobile-air-classifier-animatedon over 80 years of experience with the stationary Whirlwind® Air Classifier and is specifically designed to effectively remove fines from aggregates including granite, concrete, gravel, and limestone without the need for screening or wet washing. Sam Rajkovich, Director of Sales & Marketing for Sturtevant, details that “the Whirlwind® Mobile Air Classifier is easy to transport with no cranes, boom trucks, or loaders needed to ready the conveyors and can go from being parked to processing in one hour.” Sam Rajkovich continues that “the compact design also allows for the machine to be taken to any job site complete with dual hydraulic cylinders for raising and lowering the air classifier and conveyors allowing for a quick and efficient setup and takedown of the machine.”

Joe Muscolino, Senior Product Manager for Sturtevant, explains that for aggregate and sand producers who own multiple quarries the Whirlwind® Mobile Air Classifier grants them “the option of bringing the machine to the quarry instead of the quarry to the machine” saving them money in transportation costs and eliminating the need for multiple, stationary machines to accomplish the same task.
