1.) Storage Silo
Astec storage systems come complete with bucket elevators, traverse conveyors, and loadout. Silo support structures are designed to meet the site specific design criteria at your location, based on the current building codes in your state. Our structural engineering staff will design your foundations, based on soil conditions at your site.
2.) Safety Handrail and Ladders
Handrails and guards meet MSHA requirements. Access platforms make it easy to service equipment.
3.) Fines Silo (Optional)
Fines can be stored in an optional dust silo for easy disposal.
The complete system consists of a primary dust collector (inertial separators or cyclone), an enclosed fabric filter structure (baghouse), and a draft package that includes the fan, variable frequency drive, and ductwork.
Veiling flights used with VFD provide greater uniformity of the sand veil through the hot gas stream.
Astec burners offer the latest in reliable burner technology, combined with complete one-source responsibility. The Astec group engineers the burners to customer specifications and manufactures each in a state-of-the-art facility.
7.) High Frequency Screen
Sealed tight to eliminate dust emission on the screen and utilizes pipe outlets at the discharge ends of the screen decks. Four electric vibrators mounted below screens, directly induce vibrating action. All vibrators have adjustable amplitude settings on adjustable slip counterweights.
8.) Collection Piles
9.) Control House and Controls
10.) Feeder Bins
Stand up to front-end loaders and abrasive materials, year after year.
Bulkheads extend the length of the bin to grade. Ample space behind the bulkhead creates a walkway for easy access. Hinged wing walls make grading to bin simple.
Dancing plate bin vibrators provide better material flow.
