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.

Elutriation - Wikipedia

Elutriation is a process for separating particles based on their size, shape and density, using a stream of gas or liquid flowing in a direction usually opposite to the direction of sedimentation. This method is mainly used for particles smaller than 1 μm. The smaller or lighter particles rise to the top (overflow) because their terminal sedimentation velocities are lower than the velocity of ...
