Pneumatic Conveying Introduction

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 Conveying - an overview | ScienceDirect Topics

1 INTRODUCTION. Pneumatic conveying of bulk solid materials through pipelines has been in use for over one hundred years. There are two distinctly different flow modes in pneumatic conveying, dilute-phase and dense-phase. Dilute-phase is used widely in industry due to its simplicity in design and operation. However, high air velocities (e.g. 20 to 40 m s −1) have to be used in suspension ...
