Sturtevant Introduces Mobile Classifying Plant

55 STURTEVANT1 150

55 STURTEVANT1 400Sturtevant Inc. introduced what it is calling the world’s only self-contained, 100-percent-mobile air classifying plant with integral collapsible conveyors, enabling parking to processing in one hour or less.

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 needed for any part of the operation. Simply push a button.

Dual hydraulic cylinders provide smooth, steady raising and lowering of the Whirlwind air classifier and the integral, collapsible feed and dual discharge conveyors.

The plant is mounted on a rugged chassis frame with tri-axle suspension for stable travel on highways or back roads. The plant is designed and constructed for vibration-free operation and long service life with low maintenance.

55 STURTEVANT2 400The compact design features a low transport height (13-ft., 5-in.), short trailer transport length (61-ft., 9-in.) and trim transport width (12-ft., 7-in.) for easy maneuvering on roadways and at job sites. Feed capacity is 30 to 90 tph with a 50-hp variable-frequency motor for low energy consumption.

Sturtevant estimates transportation costs at 40- to 50-percent lower than if they had designed a larger plant with unattached conveyors requiring assembly.”

Other features include a long, high main discharge conveyor for greater stockpile heights and a low feed conveyor intake hopper that can be fed by a front-end loader. The feed hopper is located behind the trailer rear wheels to prevent spillage of feed material onto the chassis. The smaller side conveyor is for byproduct fines.

For safety and nuisance dust control, all three-belt conveyors are covered and can be easily vented. The conveyor covers also help reduce moisture during rain to ensure efficient performance. The air classifier is designed for dry operation. Material moisture preferably should not exceed 2 to 3 percent, with 4 to 5 percent as maximum for most materials.
