Aeration troughs are used to promote consistent product withdrawal from large diameter flat or conical bottom storage silos. The aeration trough 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. Troughs are typically mounted inside the conical section of the silo and are equally spaced along a 360 degree pattern. However they can also be used in flat bottom silos and only require a 6 degree slope from the inner silo wall of the silo to the discharge point. 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 [649° 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 selection of aeration troughs from 6 inches [152 mm] wide up to 24 inches [610 mm] wide.

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