ABSTRACT:
A method and jet mill apparatus for generating fine particles by means of a jet mill with an integrated dynamic air classifier including a classifying wheel classifying wheel shaft and classifier housing, wherein between the classifying wheel and classifier housing a classifier gap is formed and between the classifying wheel shaft and the classifier housing a shaft passage is formed, wherein gap flushing of classifier gap or shaft passage takes place with compressed gases of low energy content, and wherein comminution jet inlets are present which are charged with energy-rich superheated steam. Through the invention a dynamic air classifier explained above and a corresponding operating method therefor are additionally created.
