Modeling the Dynamics of Vibratory Separator of the Drum Type with Concentric Arrangement of Sieves

In order to provide for a more efficient process of separation, we propose a new type of separator, in particular separator of the drum-vibratory type. It has a number of advantages over other separators:1) characterized by simplicity of design and maintenance;2) low sensitivity to the properties of the separated mixture;3) a variety of oscillation modes;4) possibility to automate the process of separation.In order to design a separator, theoretical study was conducted into its dynamics for the purpose of examining the impact of its structural and kinematic indicators on the intensity of separation process of bulk mixtures. This problem was solved by constructing a nonlinear mathematical model that describes dynamics of the separator. The model is built based on a number of mathematical methods and laws, in particular the asymptotic methods of nonlinear mechanics. It is a system of non-linear analytic expressions, which in character format includes kinematic and geometric parameters of separator. Based on the model and our studies, we selected parameters for a vibratory separator of the drum type, which will provide the most effective separation of mixtures according to the selected criteria.The developed mathematical model is uniform and parameterized. It allows speeding up the process to design a separator. It can be also used for designing and selecting the operation modes of separators of different types with a vibration drive, as well as for other vibratory processing machines
