Description
Introduction:
A Pneumatic Conveyor is an advanced material handling system that transports bulk materials through pipelines using air or gas as the conveying medium. It is widely used for handling powders, granules, and fine materials in a clean, enclosed, and controlled manner. Pneumatic conveying systems are ideal for applications where hygiene, dust control, and flexible routing are critical.
At Tech Trek Engineering, we design and manufacture pneumatic conveyor systems that are efficient, reliable, and fully customized according to material properties, conveying distance, and plant layout. Our pneumatic conveyors are engineered for safe operation, minimal material loss, and consistent performance in demanding industrial environments.
What is a Pneumatic Conveyor?
A pneumatic conveyor is a conveying system that moves material through a closed pipeline using air pressure or vacuum. Instead of mechanical components like belts or screws, pneumatic conveyors rely on airflow to carry materials from one point to another.
These systems are especially suitable for transporting fine, dusty, or fragile materials while maintaining a clean and hygienic working environment.
Working Principle:
The working principle of a pneumatic conveyor depends on the conveying method:
Positive Pressure Pneumatic Conveying
- Material is fed into the conveying line through a feeder.
- Compressed air pushes the material through the pipeline.
- Material travels at controlled velocity.
- At the discharge point, air and material are separated using a cyclone or filter receiver.
Vacuum Pneumatic Conveying
- A vacuum source creates negative pressure in the pipeline.
- Material is sucked into the conveying line from the source.
- Material travels through the pipeline to the receiver.
- Material is discharged, and air is filtered before release.
Both systems ensure enclosed, dust-free material transfer.
