Pneumatic Vacuum Conveyor for Automated Powder Loading

Product introduction of Pneumatic Vacuum Conveyor

Pneumatic Vacuum Conveyor is an advanced pneumatic conveying system designed for the automatic transfer of powder, granule, and bulk materials in various industrial production processes. The system uses negative pressure generated by a vacuum source to create airflow, drawing materials from the feeding point and transporting them through a closed pipeline.

During operation, the material and air mixture enters the conveyor system, where the filter separates the product from the conveying air. The clean air is discharged through the vacuum unit, while the separated material falls into the receiving hopper or connected production equipment.

Compared with traditional manual feeding methods, the Pneumatic Vacuum Conveyor provides a cleaner, safer, and more efficient material handling solution. The enclosed conveying structure helps prevent dust leakage, reduces contamination risks, and improves the working environment.

The system can be integrated with various production machines, including tablet presses, capsule filling machines, packaging machines, mixers, vibrating screens, granulators, crushers, and storage silos. Its compact structure, automatic operation, and flexible configuration make it suitable for modern automated production lines.

With customizable materials, hopper sizes, control systems, and explosion-proof options, the pneumatic conveying system can meet different production requirements in industries requiring reliable and hygienic powder handling.

Working Principle

The Pneumatic Vacuum Conveyor works based on vacuum suction and airflow transportation technology.

• The vacuum generator creates negative pressure inside the conveying pipeline.
• The suction force draws powder or granular materials from bags, containers, hoppers, or storage units.
• Materials are transported together with airflow through the sealed conveying pipe.
• The filter system separates materials from the air stream.
• The material enters the receiving equipment through the discharge valve.
• The filter is automatically cleaned by compressed air backflushing to maintain stable conveying efficiency.
• The system repeats the conveying cycle automatically.

This working method ensures continuous, clean, and reliable material transfer.
