The level of accelerations of sieving surfaces of vibrating screens for effective separation finelydispersed bulk materials is determined. The levels of natural frequencies of the particles that have adhered to a sieving surface or bound among themselves under effect of surface forces of a liquid are established. Influencing polyfrequency oscillations of sieving surfaces of vibrating screens on separation of bulk materials is reviewed. Are rotined of advantage of a continuous spectrum of excitation of surfaces above monofrequency or narrow discrete.
