Plug Flow Dense Phase Conveying System
Product Details
The gas velocity which can form plugs changes with conveying pipe size, particle size, bulk density, gas density (pressure) etc. In case of polyolefin (for example polypropylene) pellets conveying, the gas velocity is a standard in 10m/sec or less. On the occasion of actual design, the range of gas velocity will be designed 2～8 m/s. In the case of powder conveying, proper gas velocity is lower about 40%～50% than the case of pellet.
Applications
The Plug Flow system is called commonly High Pressure System, because it is frequently applied to long distance conveying that it is required high pressure which is used compressor as air source. However, conveying pressure depend on conveying distance. Even pressure becomes low, if distance is short. In this case, roots blower can be applied with stabilize conveying. Also we can adopt standard (for low pressure) rotary feeder(or blow tank for low pressure) as conveying feeder in this Plug Flow System.
OUR PRODUCTS
Suspension (dispersion) Flow Dilute Phase Conveying System
The Floating Flow conveying is categorized Dilute phase Conveying System that the gas velocity inside conveying pipe is fast and powder/pellets move with floating.
Dune Flow Dense Phase Conveying System
The Dune Flow conveying is high density conveying system that powder/pellets moves while making slug movement with group style form like a sand dune at the bottom of conveying pipe. In the case of coarse (large) powder and pellets, the formation principle is almost similar with Plug Flow. But the difference point against Plug Flow is no closing by particle groups or very few in the section of conveying pipe.
Layer Flow Dilute Phase Conveying System
In floating flow, Layer Flow means comparatively low (Middle) gas velocity and collected powder/pellets at the bottom of conveying pipe. The Layer Flow has some advantage over Suspension Flow such as ①high mixing ratio and high conveying efficiency ② low conveying material damage ③ low conveying pipe abrasion.
Use primary airflow is used as a part of classification airflow. It has higher classification performance than the swirling current classifier.
