Introduction to Pneumatic Conveying of Solids

Introduction to Pneumatic Conveying of SolidsKarl JacobThe Dow Chemical CompanyEngineering Sciences/ Solids ProcessingMidland, for this webinar Understand various modes of Conveying of Solids Learn how to decide on Conveying configuration Examine key aspects of design of Conveying systems Recognize the various Conveying system components Learn how to approach common Conveying problemsWhat 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.

Conveying Fundamentals In contrast to fluid flow with liquids, the conveying gas expands along the length of the pipe and that has a considerable effect of the design and operation pneumatic conveying systems Contributions to pressure drop in a conveying system −Head loss due to elevation change −Solids acceleration −Gas friction loss
