Pneumatics - Transport of Solids and Separator Types
Separators used in pneumatic solids transport systems and their minimum particle size.
In a pneumatic transport system, solids like dust, flour, sugar, sand and many other products, are transported in a high speed air flow.
The table below can be used to indicate minimum particle size recommended for different types of separators.
| Separator Principle | Minimum Particle Size (micron) |
|---|---|
| Gravity | 200 |
| Inertial | 50-150 |
| Centrifugal, large diameter cyclone | 40-60 |
| Centrifugal, small diameter cyclone | 20-30 |
| Fan type | 15-30 |
| Filter | 0.5 |
| Scrubber | 0.5-2.0 |
| Electrical | 0.001-1.0 |
- 1 micron = 0.001 mm
