Dwyer BAP - Manual

Bulletin PC-BAP
Series BAP Bin Aerator Pad provides positive flow of dry, finely
ground materials from any bin using the proven principle of
aeration. Low pressure air is introduced into the product, restoring
its natural ability to flow. In this way congestion, bridging and rat-
holing 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. Series BAP is
non-clogging and provides equal distribution and consumption of
air. The aerator pads feature simple and quick installation, are
inexpensive, and adapt to any bin configuration.
There are many advantages of the Bin Aerator Pad. It provides a
positive, uniform, and easily controlled flow with quiet operation.
Also, it yields first in/first out flow. Heavy-Duty construction
features stiffeners to prevent crushing of air compartment. These
stiffeners eliminate the possibility of the Bin Aerator Pad being
crushed by a head of material or by a man stepping on it when
cleaning bin. The stiffeners do not obstruct the diffusion of air.
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 content are as follows: Lime, Portland
Cement, Carbon Black, Diatomaceous Earth, Flour, Soda Ash,
Gypsum, Fly Ash, Pigments, Soap Powders, Bentonite, Bran,
Clay, Cereals, Fullers Earth, Detergents and many others.
