20090236451Method For Generating Finest Particles And Jet Mill Therefor As Well As Classifier And Operating Method Thereof - A method and jet mill apparatus for generating fine particles by means of a jet mill with an integrated dynamic air classifier, wherein the rotational speed of a classifying rotor of the air classifier and the inner amplification ratio V (=Di/DF) are so selected, set or controlled that the circumferential velocity of the operating medium at an immersion pipe or outlet connection assigned to the classifying wheel reaches up to 0.8 times of the velocity of sound of the operating medium. A dynamic air classifier with a classifying wheel is additionally created, wherein a source (Tank 09-24-2009
20090261187METHOD FOR GENERATING FINEST PARTICLES AND JET MILL THEREFOR AS WELL AS CLASSIFIER AND OPERATING METHOD THEREOF - 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.10-22-2009
