dc.description.abstract | The high-temperature-uncooled-developed air jet mill system (AJMS) is one of the most effective grinding technologies for uniformed particle size. AJMS is the core technology in raw material manufacturing technology to grind and classify materials efficiently with a classifier that crushes raw materials by high-pressure compressible nozzles at high temperature into micro size particles and separates them by the desired size by using the centrifugal force of the rotor. However, the characteristics of grinding and classifying are affected by internal factors with occurring of complexed physical phenomena. To overcome the challenge, we used a discrete element model (DEM) and Computational fluid dynamics (CFD) simulation to clarify the relationship of the correlation with the actual design variables by predicted the motion of particles with the operating conditions and obtained optimized conditions. This research is described pulverization models of the AJMS with particle-structure interactions through optimized design value from DEM. Based on these results, we suggest a design method of AJMS to grinding the ceramic particles 2.86 mu m of an average and 1.32 mu m of a standard deviation from 14,000 rpm of the classifying rotor.
