Aeration conveyors are used to gravity convey powders by passing low pressure air through a porous membrane media and into the bed of the material being handled. A large variety of materials can be handled 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].
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 m?] is required to conduct a proper test.
DCL offers a large selection of aeration conveyors from 6 inches [152 mm] wide up to 36 inches [914 mm] wide and conveying capacities up to 1000 cubic feet per minute [28.3 m?/min]. Conveyors also are available in a high top or low top design allowing for maximum flow rate or minimum head room depending on the application.
A choice of construction materials allow handling of all types of products; fine, granular, lumpy, abrasive, corrosive, and sanitary applications.
