Key Components of Dilute Phase Pneumatic Conveying Systems:

Material Feeding Device: The bulk material is typically fed into the pneumatic conveying system using a feeder, such as a rotary valve, screw conveyor, or gravity feeder, which meters the material into the conveying line at a controlled rate.

Conveying Pipeline: The conveying pipeline is a closed-loop system consisting of straight sections, bends, elbows, and other fittings. The pipeline is designed to transport the material from the feed point to the destination, often spanning long distances horizontally or vertically.

Air Supply: A supply of compressed air or gas is used to generate the high-velocity air stream required for conveying the material through the pipeline. The air is injected into the pipeline at a controlled pressure and velocity, creating a pneumatic force that suspends and carries the material.

Material Separation and Collection: At the destination point, the material is separated from the conveying air using a separator, such as a cyclone separator or filter receiver. The separated material is then discharged into a storage vessel, process equipment, or packaging system, while the conveying air is either recirculated back into the system or discharged into the atmosphere.

Operation of Dilute Phase Pneumatic Conveying Systems:

In dilute phase pneumatic conveying systems, the bulk material is entrained in a high-velocity air stream and transported through the pipeline in a suspended or fluidized state. The air velocity is typically maintained above the minimum conveying velocity required to keep the material in suspension, but below the saltation velocity at which the material would settle out of the air stream.

Applications of Dilute Phase Pneumatic Conveying Systems:

Food Processing: Conveying flour, sugar, spices, grains, and other food ingredients.

Pharmaceutical Manufacturing: Transporting powders, granules, and active pharmaceutical ingredients (APIs).

Chemical Processing: Conveying catalysts, pigments, resins, and specialty chemicals.

Plastics Processing: Transporting plastic pellets, powders, and additives in polymer production.

Agriculture: Conveying grains, seeds, fertilizers, and animal feed ingredients.

Mining and Minerals: Transporting ores, minerals, cement, and aggregates in mineral processing plants.
