Mobility added as feature to air classifying plant

The self-contained Whirlwind mobile air classifying plant features collapsible conveyors and enables parking to processing in one hour or less, according to Sturtevant Inc. The Whirlwind air classifier and conveyors hydraulically unfold for setup and fold away for breakdown and transport with no cranes, boom trucks, front-end loaders or special crew, the company says. Dual hydraulic cylinders provide smooth, steady raising and lowering of the Whirlwind air classifier and the collapsible feed and dual discharge conveyors, Sturtevant adds. According to the company, the plant is mounted on a rugged chassis frame with tri-axle suspension for stable travel on highways or back roads. The plant’s compact design features a transport height of 13 ft., 5 in.; a trailer transport length of 61 ft., 9 in.; and a transport width of 12 ft., 7 in. Feed capacity is 30 to 90 tph with a 50-hp variable-frequency motor.
