摘要

PURPOSE: A jet mill is provided to effectively prevent a particle, which has a larger size than the size of powder particle passing through a classifier, from passing through an interval of a jet mill inner body and a radial rotor by including a blade in the radial rotor of the classifier.;CONSTITUTION: A jet mill comprises a grinding chamber(1) which is composed of a chamber body(11), a material supply pipe(12), and a chamber cover(15); a classifier(2); a spray nozzle combination(4) which is combined with a nozzle combining hole(111) of the grinding chamber and includes the spray nozzle; an air supply device(3) including an air connecting tube(33) which supplies the air of high pressure to the spray nozzle combination; and a drive unit(5) consisting of a drive motor(51) and a transmission gear.;COPYRIGHT KIPO 2010
