Abrégé

A method for producing graphite particles of certain, different fineness classes rounded by impact effect, with the help of several spheroidal separators, which are connected in series, wherein the graphite material to be rounded is pre-comminuted, and from this, a first spheroidal separator then produces graphite material, which is spheroidized by means of folding, of a first fineness class, which is discharged from the method as end product, and simultaneously separates graphite material, which can predominantly not be processed to graphite material of this first fineness class because it is too comminuted, wherein the separated graphite material, which is too comminuted, is fed to a second spheroidal separator, which, from this, can produce graphite material, which is spheroidized by means of folding, of a second, finer fineness class, which is likewise discharged from the method as end product.

Abrégé

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.

Abrégé

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.
