Tarasenko V. Simulation of the working process and optimization of parameters of the mining single-roll crusher for rock of strong

Single-roll mine gyratory crusher for rock of strong. Research of legitimacies of the working process of mine gyratory crushers, selection of optimum structure and parameters ensuring the decrease of dynamic loads and increase of the technological level of crushing machine. Computing experimental researches with usage of an imitative mathematical model of operation of the crusher. The methods of statistical non-linear dynamics, theory of stochastic processes, theory of multitudes, solution of systems of differential equations by the numerical method, methods of mathematical statistics and probability theories were used. An imitative mathematical model of operation of the single-roll crusher taking into account transients in the drive of the crusher for the first time is developed at its start, in steadied activities and at locking the actuator by the not crushed subject. The availability of resonant modes of operation is detected and the statistical characteristics of loads in steadied activity of the crusher are established. Is established, that the selection of parameters of shear pins of preventers should be executed on the basis of the actual diagrams of their deformation and transient regimes of activity of the drive. The fast-track and strength parameters of loading of shear units of preventers are determined. The outcomes of researches utilized by institute Dongiprouglemash at preparation of tests of an experimental sample of the single-roll crusher DV, at operational development and analysis of paths of further perfecting, and also DonSTU at realization of research works and in educational process. An orb (area) of usage - at plants and project institutes of mining machinery manufacturing of Ukraine, in educational process.
