The powder-assisted air pad can effectively prevent arching phenomena such as bridging and rat-hole blockage of materials in the cone storage tank (silo). Because there are many honeycomb-shaped micropores on the surface, when compressed air is introduced, the air flows out along the honeycomb holes, giving a pulse-shaped airflow impulse (0.2bar) to the accumulated materials at the bottom of the cone, allowing the materials to float and increase the flow of the materials , So as to smoothly flow out of the tank.
