Nonlinear mathematical models of these structures of vibrating technological systems are constructed. The models are unified and parametric. Its structure in character format includes geometric and kinematic parameters of the separator. This model allowed us to explore influence of the separator parameters on the character of motion of its sieves (the drum of separator) during its operation. It was established which parameters of the separator provide for the motion of sieves with maximum continuous tossing and stirring the mixture in them. The given character of the sieve motion ensures the fastest process of separation and unloading of the separated fractions out of the separator. We relate to the indicated parameters: angular speed and weight of debalances, the magnitude of their eccentricity, rigidity of suspension, the magnitude of oscillatory mass, geometric characteristics of the separator. The latter include position of the suspension and debalances. The adequacy of the constructed nonlinear mathematical model for vibratory separator of the drum type was experimentally confirmed in terms of reflecting the oscillatory processes in it. A mean relative error when comparing theoretical and experimental results does not exceed 15.2 %. It is established that the formation of motion character of the separator sieves and separator as a whole is determined by the dominant frequency of external disturbance – frequency of debalance rotation. The character of oscillatory motion of the separator is also affected by the motion of mixture in the sieves, though this impact is not significant.
