Before You Design An Inertial Separator: Measuring Your Dust'S Aerodynamic Particle Size

Predicting how dust particles will act in air (or other gas) stream - that is, their aerodynamic behaviour - is all important for designing cyclones and venturi scrubbers. Both of these dust control units operate as inertial separators, which must be designed for a dust's aerodynamic particle size distribution to successfully separate the particles from air. After introducing some aerodynamic particle size basics, this paper gives practical information on measuring your dust's aerodynamic particle size, correlating sizing results, and using the results to design your inertial separator.
