Item: Aeration Trough






DCL's Aeration troughs are used to promote consistent product withdrawal from large-diameter flat- or conical-bottom storage silos. It works 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. 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 domes and rectangular storage buildings and only require a 6 degree slope from the inner wall of the silo to the discharge point.


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. You can handle a large variety of materials with aeration conveyors regardless of their abrasive nature or bulk density. 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].


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.


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 allows you to effectively handle all types of products – fine, granular, lumpy, abrasive and corrosive – and difficult dusty or sanitary applications.
