[0002] A jet mill is a device that uses high-speed airflow to crush materials. In a jet mill, the gas nozzle device is one of the key components. It is responsible for converting high-pressure gas into high-speed airflow, thereby crushing the material. During operation, the nozzle will wear out and need to be replaced.

[0003] Most of the current gas nozzle devices used in air jet mills have nozzles directly welded to the air jet mill, which makes disassembly and assembly of the nozzles inconvenient and time-consuming. In addition, the nozzles are made of poor material and are prone to wear during use, resulting in a short service life.
