%X The structure and parameters of the nozzle of a jet mill device are optimized, numerical simulations of the inner structure are carried out with hydrokinetics software, the stress analysis of the structure is conducted with finite element software, and the effects of inlet diameter, section area of throat region, passage shape and diffusion angle on supersonic nozzle are analyzed. Optimized operation parameters include pressure of 3.5\,MPa and inlet diameter of 6\,mm after comparing different simulations. In the range of $8^\circ \sim 12^\circ$, the diffusion angle has little effect on the performance of the designed supersonic nozzle.
