Pneumatic Vacuum Conveyor Solution for Powder Feeding Process

Product introduction of Pneumatic Vacuum Conveyor

Pneumatic vacuum conveyor is an advanced enclosed material handling system designed for efficient and contamination-free transfer of powders, granules, and small pellets. It operates using negative pressure airflow generated by a vacuum pump, which transports materials through a sealed stainless steel pipeline from one process point to another. The system integrates a conveying pipe, vacuum unit, filter chamber, and intelligent control system to ensure stable and continuous operation. Widely used in food, pharmaceutical, chemical, and plastic industries, it enables automated feeding to mixers, grinders, packaging machines, and storage silos. By reducing manual handling, dust emission, and material loss, it significantly improves production efficiency, hygiene standards, and overall process automation in modern industrial environments.

Working principle

Step 1: Vacuum Generation
The vacuum pump generates negative pressure inside the sealed pipeline system.

Step 2: Material Feeding
Powders or granules are introduced into the suction inlet from storage or processing equipment.

Step 3: Airflow Transport
Negative pressure airflow pulls materials into the pipeline system.

Step 4: Pipeline Conveying
Materials are transported through stainless steel enclosed pipelines safely.

Step 5: Separation Process
At the discharge unit, air and materials are separated efficiently.

Step 6: Material Discharge
Materials fall into target equipment such as mixers, hoppers, or packaging machines.

Step 7: System Reset
The system automatically resets for the next conveying cycle.
