Air classifier - Wikipedia

An air classifier is an industrial machine which separates materials by a combination of size, shape, and density.. It works by injecting the material stream to be sorted into a chamber which contains a column of rising air.Inside the separation chamber, air drag on the objects supplies an upward force which counteracts the force of gravity and lifts the material to be sorted up into the air.
