A monoaxial vibrating motor placed transversely on a sifter as a vibration source of a high speed sifter was developed in this paper. The sifter with such structure has good characteristics, such as excellent sieving performance, simple structure, balanced running and low energy consumption. Especially, through adjusting setting position of the motor on the sifter, we can change the moving state of the sifter surface and achieve a high sieving performance. According to the experiments, the main parameters of structure that affect sieving performance were found out and the principle of these effects was described. Through a polynomial regression analysis to the results, the effects of the parameters on sieving performance, the rule of sieving performance, and the changing range of optimum parameter of the structure were also obtained.
