Model AD Aeration Pad - AD-C, AD-F

Concrete batch plant cement silo 7.5" x 3.75" aeration pads or are used to provide a means of introducing low pressure air into a dry bulk materials such as cement or flyash. The air helps restore the material's natural ability to flow once the dry material becomes compacted in the cone of a silo or cement weigh hopper.

Aeration pads are the most cost effective way to promote material flow and the aerator pads use a minimum amount of air that is typically 6.5 cfm at 3 psi.

Aeration on Cement Silos for Ready Mix Concrete Plants:
Typically, 6 aeration pad assemblies are recommended in the cone of a main or auxilliary cement or fly ash silo. Gravity cement weigh batchers and cement silo cones are equipped with aeration pads in the batcher that can typically be mounted from a small rectangular hole on the outside of the weigh hopper. The aeration pads receive their air typically from a low pressure blower operated by a single acting electric over air solenoid valve, the electrical signal for this valve should be a maintain button. Aeration for the cement scale should be activated by the batch control at the beginning of the material weigh up process and remain on until the scale is empty at the end of discharge cycle. A regulator will be located along with the solenoid valve for aeration; approximately 8 PSI is recommended for the aeration. It is important when dealing with high pressure air being used for aeration that the air is non-lubricated, dry and filtered. Using non-lubricated, dry and filtered air for cement or fly ash silo aeration will increase the life of the air pads and increase discharge speed.

- Model AD Aerators provide positive flow of dry, finely ground materials from any bin using the proven principle of aeration.
- The advantages of aeration are: 1) Inexpensively adapts to any Bin Configuration 2) Quiet Operation 3) Low Power Required 4) Easily controlled uniform flow 5) Simple Installation
- When low pressure air is introduced into the product, restoring its natural ability to flow., congestion and product packing are overcome without resorting to brute force. Almost all flow problems inherent to dry, fine materials are caused by compaction of the material. When low pressure air is introduced to a finely ground material it will flow like water, uniformly and quickly. Model AD Aerators are non-clogging and provide equal distribution and consumption of air. They feature simple and quick installation. Simply cut a small rectangular slot in bin wall, insert a special mounting kit and tank nipple through the slot and secure the pad and external mounting kit with a lock nut.
