Pneumatic Conveying may be defined as the art of transporting dry bulk materials through a pipeline by either a negative or a positive pressure air stream. It is also described as harnessing air movement to accomplish the conveying task. The air (pneumatic) movement is nothing more than air in motion. Pneumatic Conveying …
