Influence of polyfrequency oscillations of screen surfaces of vibrating screens with a solid frequency spectrum on efficiency of separation finedispersed bulk materials has been reviewed. The mathematical model of a polyfrequency vibrating screen has been designed, the modes of excitation of screen surfaces have been studied. The conditions of polyfrequency excitation of screen surfaces with a solid frequency spectrum have been determined. The stability of polyfrequency oscillations against changes of technological load and dynamic parameters of a screen has been substantiated.
