Aero conveyors solve some of the biggest problems associated with conveying friable materials by combining features of mechanical and pneumatic conveyors. This article discusses these problems, explains an aero conveyor's function, provides tips for conveying friable materials, and discusses advantages and disadvantages of aero conveyors and dilute- and dense-phase pneumatic conveyors.
Friable materials such as some chemicals, pharmaceuticals, and foods can degrade, segregate, and generate dust during in-plant conveying and handling. While pneumatic conveying is commonly used for in-plant conveying and easily controls the dust, only dense-phase, high-pressure pneumatic conveying can overcome degradation and segregation problems. But such a system has a high capital cost, particularly for a short conveying distance. A more economical solution for conveying a friable material across a short distance is an aero conveyor.
