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.

Pneumatic Powder and Solids - Transport Systems
Some common solids as flour, sugar, cement and many more, can be suspended and transported in air - referred to as pneumatic conveying. A pneumatic conveying system may transport solids up to approximately 50 mm in size. The powder or solid must be dry with no more than 20% moisture and not sticking.. In a pneumatic conveying system most of the energy is used for transport of the air itself.
