Aeration pads, also known as air pads or air blasters, are devices used in material handling and storage systems to improve the flow of powders, granules, and other bulk solids. They typically consist of a porous membrane made of rubber, silicone, or other materials that allow air to pass through. The pads are placed in the bottom of a silo, hopper, or other container, and then connected to a compressed air supply.
When activated, the pads release short bursts of compressed air into the material, which causes it to fluidize and flow more easily. This can help to prevent bridging, rat-holing, and other flow problems that can occur with certain types of powders and granular materials. Aeration pads are commonly used in industries such as food processing, pharmaceuticals, chemicals, plastics, and cement production. They can also be used in conjunction with other flow aid devices, such as vibrators and air cannons, to provide more effective material flow control.
