摘要
A method and apparatus for generating fine particles via 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 for an operating medium is a fluid, more preferably a gas or a vapour, which has a higher and more preferably a substantially higher velocity of sound than air.
