JET MILL
Document Type and Number:
WIPO Patent Application WO/2012/014985
Kind Code:
A1
Abstract:
Disclosed is a jet mill that has a cylindrical pulverization chamber (10) and a classification chamber (6) that connects to the pulverization chamber (10). A fine-powder discharge port (4a) and a classification rotor (7) are provided in the classification chamber (6). A feedstock supply port (5) and at least one gas jet nozzle (11) are provided in the pulverization chamber (10). The shape of the classification chamber (6) is a cone that starts on the inner wall of the pulverization chamber (10) and is angled towards the classification rotor (7). This configuration gives the jet mill a high pulverization efficiency and reduces the amount of powder left in the chamber when the jet mill has finished running.
