Abstract
Disposed is a jet mill that has a cylindrical pulverization chamber () and a classification chamber () that connects to the pulverization chamber (). A fine-powder discharge port () and a classification rotor () are provided in the classification chamber (). A feedstock supply port () and at least one gas emission nozzle () are provided in the pulverization chamber (). The shape of the classification chamber () is a cone that starts on the inner wall of the pulverization chamber (), and is angled towards the classification rotor (). This configuration gives the jet mill high efficiency of pulverization and reduces the amount of powders left in the chamber when the jet mill has finished running.
