Overview
Model AD Bin Aerators provide positive, first in/first out flow of dry, finely ground materials from any bin using the proven principle of aeration. Low pressure air is introduced into the stored product, restoring its natural ability to flow. Congestion, bridging, and ratholing are overcome without resorting to brute force. Almost all flow problems inherent to dry, fine materials are caused by compaction. When low pressure air is introduced to a finely ground material it will flow like water, uniformly and quickly. Heavy-duty construction features stiffeners to prevent the crushing of the AD’s air compartment. These stiffeners eliminate the possibility of the Aerator being crushed by the weight of material, or by personnel stepping on it when cleaning the bin. The stiffeners do not obstruct the diffusion of air. Model AD Aerators are non-clogging, adapt to any bin configuration, and provide equal distribution and consumption of air. Model AD Aerators are maintenance-free, easily controlled, and quiet.
NEED TO KNOW
Aeration gives the best results on materials with a 60-mesh size or smaller and with a 3% or less moisture content. Specific materials that respond well to aeration include: Lime, Portland cement, carbon black, diatomaceous earth, flour, soda ash, gypsum, fly ash, pigments, soap powders, bentonite, bran, cereals, fuller’s earth, clay, detergents, and many others. AD Aerators are quick to install: simply drill a 7/16" hole in bin wall, insert special tank nipple through hole and secure with lock nut. To simplify installation even further, use the AD-K Bin Aerator Mounting Kit.
For the best results, locate lower Aerators as close to the discharge outlet as possible. If material is held in the bin for long periods and/or compacted in transport, it is recommended that Aerators be installed on 12" centers. The air supply must be clean and dry. We recommend positive displacement, low pressure blowers. Plant air can be used, but the pressure must be reduced to 3 to 5 PSI and a filter or moisture trap used on the low-pressure side. The volume of air needed can be a limiting factor when using plant air.
