Twice internal classification can obtain fine powder and uniform particle size-disdribution.

                                                    QON Circulation Tube Type Jet Mill 

Principle:

Jet stream formed by compressed-air through feed injector suck the powder material ito grinding chamber and inject to chamber of lower of "O" cycle across the Venturi tube. he pulverizing nozzles installed round the grinding chamber inject high-speed stream to grinding chamber, the stream makes powder material pulverized by the action of impaction and friction betweem powder materials. Pulverized fine powder rise along with the stream through the rising tube into the primary classifying chamber. The centrifugal force makes large particles down return to grinding chamber, Been broken away from the rotational flow, fine powder comes into the collection system through center discharge tube.
