A pneumatic conveyor is a system that uses compressed air or vacuum to move dry, granular, or powdered materials through a pipeline. Pneumatic conveyors are used in factories and plants to move materials from one place to another.
Works
- A fan or blower is connected to a series of flexible pipes
- Compressed air or vacuum is used to move the material
- The material is conveyed through the pipeline to a receiver
- The receiver disengages the material from the carrier gas
What it's used for
- Moving materials like flour, cement, sugar, and plastic pellets
- Loading and unloading industrial machines
- Distributing powders at multiple points
- Separating dust
Advantages
- Safe: Fewer moving parts and low maintenance make pneumatic conveyors safer for operators
- Compact: Pipelines are easy to route and take up less space than mechanical systems
- Flexible: Can be designed to route around bends and corners
- Upgradable: Can be easily modified with design changes
- Dust free: Material stays inside the enclosed pipeline, so there's no spillage or leakage
What to consider
- The right system depends on the material and distance being conveyed
- Moist or heavy materials are not suitable for pneumatic conveying
