Dense-phase conveying | Processing Magazine

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. The bulk material moves in the form of compact slugs
