An introduction to dry powder classification
Dynamic air classifiers. A dynamic air classifier uses the principles of elutriation, drag force, and centrifugal force to separate materials into coarse and fine fractions. A dynamic air classifier can classify a wide range of materials with particle sizes from 3 to 100 microns and can operate either inline or offline, depending on the process.

How To Separate Sand And Gravel?
Density separation methods capitalize on the difference in density between sand and gravel. a. Air Separation: Air classifiers or air separators use airflow to separate lighter sand particles from denser gravel particles. The materials are introduced into an upward-moving air stream, causing the lighter particles to be carried upwards, …
