Device used in powder coating manufacture to aid in particle size management. Air, Compressed Air at any pressure greater than atmospheric pressure.
A process in which an air stream of controlled velocity is used to separate powder into particle size fractions.
Air classification: The separation of powder into particle size fractions by means of an air stream of controlled velocity.
the separation of mixed waste materials using a moving stream of air, light wastes are carried upward while heavy components drop out of the stream.
The most common means for separation of specific size classes of PIM powders by differential settling in a high velocity air stream.
