Aeration bin bottoms are used to promote consistent product withdrawal from large diameter flat or conical bottom storage silos. The aeration bin bottom accomplishes this by passing low pressure air through a porous membrane media and into the bed of the material being handled. The low pressure air is then passed up through the material in the silo giving it a fluid type property. A large variety of materials can be handled with aeration conveyors regardless of their abrasive nature or bulk density. The criteria are particle size and moisture content. Generally a product should have a particle distribution of 100% through a 20 mesh screen. Moisture content should be below 1% and temperature can not exceed 1200 degrees Fahrenheit [649º C].

The absence of moving parts and low power requirements make air gravity conveying the most economical means to convey fine materials over short or long distances. DCL offers product compatibility tests in order to determine optimum conveying angles and aeration volumes. A minimum product amount of 2 cubic feet [0.07 m³] is required to conduct a proper test.

DCL offers a large selection of aeration bin bottoms from 2 feet [610 mm] in diameter up to 16 feet [4.9 m] in diameter. Bin bottoms are also available with custom discharge configurations allowing for multiple conveyor runs from one silo.

A choice of construction materials allow handling of all types of products; fine, granular, lumpy, abrasive, corrosive, and sanitary applications.
