Air classifier - Wikipedial

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.

Dynamic Classifier | Loeschel

Efficient classification is particulary important in power station applications; a steep product particle characteristic curve ensures that optimum combustion is achieved in the boiler while keeping emission rates at a low level. Loesche dynamic classifiers can be fitted to any type of coal mill.
