Dense-phase conveying
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.
Common Differences Between Dilute Phase Pressure Conveying and Dilute
Why Choose Pressure Conveying. Our dilute phase pneumatic conveying systems use large amounts of low-pressure (<15 PSIG) to convey materials. In this method, a blower at the system's start supplies a high volume of low-pressure air to the system, and material is fed into the conveying line through a rotary airlock valve.
