Pneumatics - Transport of Solids and Separator Types

Separators used in pneumatic solids transport systems - 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 PrincipleMinimum 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
