Pneumatic Powder Conveying System

Pneumatic Powder Conveying System is designed to transport powdered materials through pipelines using controlled airflow. The system forms a closed material transfer route, allowing fine powders to be moved between storage, processing, and packaging equipment without the need for a mechanical conveyor along the entire conveying path.

Powder is introduced into the conveying line through a feeder or pressure vessel. Airflow suspends or carries the particles through the pipeline toward the receiving point. At the destination, the powder is separated from the conveying air by a filter receiver, cyclone, or other separation device before entering the next process stage.

The conveying method can be selected according to powder characteristics. Dilute-phase conveying uses a higher air velocity to keep particles suspended, while dense-phase conveying transports powder at a lower velocity with a higher material-to-air ratio. The appropriate method depends on particle size, bulk density, flowability, moisture, abrasiveness, and sensitivity to degradation.

System configuration is also affected by conveying distance, elevation changes, required throughput, pipeline diameter, pressure, and the number of feeding or receiving points. Diverter valves and branch pipelines can be incorporated where powder needs to be distributed to multiple destinations.
