Rectangular Air Pad

For best results in promoting the flow of dry bulk powders, multiple rows of air pad bin aerators should be used. The number of rows and quantity of air pads in each row will differ by application. Monitor application engineers are ready to provide you with the best recommendation for your specific material flow problem. 
Generally, four rows of air pad bin aerators on 12 inch (305mm) or 15 inch (381 mm) centers is recommended. While the effective radius of each air pad is approximately 10 inches (254 mm), the air pads should be spaced so that the entire troublesome area is within the sphere of influence of the air pads.

 

Principle of Operation  
The Air Pad operates by continuously introducing air into the body of the dry powder. When a powder is first conveyed into a storage vessel it is actually a highly aerated mixture of air and particulate. In this state the mixture flows quite readily. However, as the powder settles the solid particulate and air separate resulting in a decrease in volume and an increase in bulk density. In this deaerated state powders can behave more like a single large solid structure rather than a fluid-like mixture. By replacing the naturally lost air, the air to particulate mixture ratio is held thus maintaining the fluid like characteristic of the aerated powder.
