Title:
JET MILL DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/067655
Kind Code:
A1
Abstract:
A jet mill device has: a hollow chamber for pulverizing objects to be pulverized into fine powder, the hollow chamber having an inner surface formed of a material having a hardness higher than that of the objects to be pulverized; and an airflow-generating section that generates a swirling airflow in the hollow chamber. The objects to be pulverized put into the hollow chamber are caused to swirl by the air flow generated by the airflow-generating section, the objects to be pulverized collide with each other, and the objects to be pulverized collide with the inner surface of the hollow chamber, thereby being turned into a fine powder. Even objects to be pulverized that have a high hardness can be pulverized.
