Summary: Among the main directions of intensification of vibrating technological action in the separation of bulk agricultural products can be noted not only the adjustment of amplitude-frequency characteristics, but also the improvement of dimensions and structural parameters of drive mechanisms. The developed scheme of the studied process of vibro screening provides an inclined location of the working tank, which allows to realize the formation of spatial oscillations of the sieve surface. The developed scheme of vibrating screen process provides an inclined location (arrangement) of the working tank, which allows to accomplish the formation of spatial oscillation of the sieve surface. An experimental model of the screen of spatial oscillations was developed and the conducted research allowed to obtain graphical dependences of energy consumption on the processing of crushed grain material on the change of mass, geometric and structural parameters of the oscillatory system. For the choice of the effective mode of vibratory screening of combined feeds, the evaluation criteria were the eccentricity of the drive shaft, the angle of the sieve surface, the amount of energy consumption and patterns of its change in terms of variation of the force pulse when changing the eccentricity of the drive shaft, the measurability of oscillating motion from flat to spatial with appropriate adjustment of the design parameters. Experimental studies have revealed the effectiveness of the use of spatial oscillations of the sieve surface in the separation of bulk masses, allowed to substantiate the design parameters of the vibrating screen
