  • Understanding dense-phase conveying I Fundamentals

    2019-7-17 · Understanding dense-phase conveying I n the world of pneumatic con-veying, there are two system types: dilute- and dense-phase conveying. Dilute-phase conveying is the most common of these two systems, due in part to its relatively straightforward design. If designed correctly, a dilute-phase conveying system can provide reliable and flex-

  • 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.
