Pneumatic Vacuum Feeder
The Pneumatic Vacuum Feeder is an industrial device that uses compressed air to drive a Venturi system to automatically convey materials. It is widely used in the plastics processing, chemical powder, food and pharmaceutical and fine chemical industries.
Unlike electric vacuum feeding systems, this equipment does not require an electric vacuum pump. It generates negative pressure through pneumatic means to achieve fully enclosed automatic conveying of powder or granular materials. It has a more compact structure and is suitable for working conditions with high requirements for explosion protection or cleanliness.
Working principle
The Pneumatic Vacuum Feeder uses compressed air to enter the Venturi generator, creating a high-speed airflow and thus generating a negative pressure environment.
The operation process includes:
- Compressed air enters the vacuum generator
- Generate stable negative pressure suction
- Material enters the conveying pipeline through the suction port.
- Gas-solid separation device separates materials from air
- The filtration system intercepts dust and cleans itself automatically.
- The entire process achieves continuous, closed-loop, and pollution-free transportation.
Applicable materials
This equipment is suitable for a variety of powder and granular materials:
- PVC/PE/PP plastic granules and powders
- Fillers such as calcium carbonate and talc
- Chemical powders and additives
- Food-grade powders and raw materials
- Pharmaceutical intermediates and raw materials
- Flammable, explosive, or explosion-proof materials (advantageous scenarios for pneumatic systems)
