Aeration Products


When cement or other fine powdered materials are first conveyed into a storage silo or bin, it is actually a highly aerated mixture of air and particulate and in this state it flows quite readily.


However, as the cement or other powder settles the solid particulate and air separate resulting in a decrease in volume and an increase in bulk density. In this de-aerated state powders behave more like a single large solid rather than a fluid-like mixture. This can result in bridging and rat hole formation, both of which prevent smooth flow.


By replacing the naturally lost air through aeration, the air to particulate mixture ratio can be maintained, thus maintaining the fluid like characteristic of the aerated powder.


To help maintain this flowability we can offer you three options, all of which provide increased flowability.


air pad, aeration product, fine powder aeration           Air Pad     

Air Pad

  • promotes material flow  

  • rugged construction

  • internal or external mounting

  • retrofit with most other brands                           

evasser, fine powder aeration, increase powder flow         Evasser  

Single Evasser

  • fluidize and dislodge materials in bins, hoppers or silos
  • air is released in the bin as well as reflected off of the wall
  • external or internal mounting

        fine powder aeration, aeration of powders

     Aeration Diffuser      


Aeration Diffuser

  • 3/8" sintered aeration diffuser plug
  • inexpensive
  • easy to install
  • provides fluidization of fine powders for trouble free discharge
