Introduction to Pneumatic Conveying of Solids

What is pneumatic conveying? Pneumatic conveying is the movement of solids through pipe using gas (usually air) as the motive force. It differs from hydraulic or slurry conveying in that the gas expands continuously along the pipe length. The flow regime in the pipe depends greatly on the ratio of solids to gas and the particle characteristics.
