Item: Aeration Bin Bottom

Aeration bin bottoms are used to promote consistent product withdrawal from large-diameter flat- or conical-bottom storage silos. It does 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 highly fluid property.

You can handle a large variety of materials with aeration conveyors. The criteria are particle size, moisture content and temperature. 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 can perform a product compatibility test for you to determine the optimum conveying angles and aeration volumes for your application. We’ll need a minimum product amount of 2 cubic feet [0.07 m³] to conduct a proper test.

We offer 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, which allow you to have multiple conveyor runs from one silo.

A choice of construction materials allows you to effectively handle all types of products – fine, abrasive and corrosive – and difficult dusty or sanitary applications.
