Understanding dense-phase conveying I Fundamentals of

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-

Dense-phase conveying Processing Magazine

Mar 29, 2017· Dense-phase vacuum has a limitation on conveying distance — 60 to 90 meters (200 to 300 feet) — based on the energy that can be produced by a vacuum blower or pump. This method is also very well suited to fragile and/or sticky materials because the material is pulled through the convey line rather than pushed, as in a pressure system.
