【Abstract】 The research is centered on the auger, the core component of TMR mixer, and introduces the structure and mixing principle of TMR mixer to determine the optimal critical speed of the auger. The finite element analysis of the auger is carried out to find out the maximum stress location and thus to bring forward the improving plan. Finally, the comparison analysis of the auger before and after the improvement is carried out, which shows that the intensity of it is qualified.更多还原
