NEGATIVE PRESSURE PNEUMATIC CONVEYING SYSTEM
The Optimal Choice for Multi-Point Vacuum Feeding
Negative pressure pneumatic conveying system (also known as vacuum conveying) uses a blower (vacuum pump) to suck air at the end of the system, creating a negative pressure lower than atmospheric pressure inside the pipeline.
Under atmospheric pressure, materials are sucked into the pipeline along with the air flow and transported to the designated location.
Key Advantages:
- Conveying Capacity: ≤ 20 t/h
- Conveying Distance: ≤ 100 m
- Applicable Materials: Low-abrasion, non-friable powders and granules
- Advantages: Simple structure, relatively low investment cost
Application Fields:
Suitable for long conveying pipeline distances and fine, granular, abrasive, non-abrasive and other difficult-to-convey materials, such as PVC powder, ternary materials, rubber powder, flour, sugar syrup, white sugar, milk powder, water-absorbent resin, lithium battery raw materials, etc.
