DETERMINATION OF THE MAIN PARAMETERS OF STRUCTURAL AND FUNCTIONAL SCHEME Kerzhencev V.A., Ph.D. (Engineering), Associate Professor, e-mail: kerjencev46@ngs.ru Perova N.V., Senior Lecturer, e-mail: perova@corp.nstu.ru Novosibirsk State Technical University, 20 Prospekt K. Marksa, Novosibirsk, 630073, Russian Federation Abstract The rationale for the design of hammer crushers with using its mathematical model is given. The dimensions of the crushing mechanism are determined by the impact factor capable of splitting particles. The densities in sectors that are breakage zones are calculated. The study is carried out on the basis of real decomposition of the dispersed composition of particles into fractions obtained at the outlet of the crushers. The functional-structural scheme of the particles flow during its crushing according to the stages of the process of changing the density is presented. The equations of mechanics are connected by the method of functional-logical connections with the equations of particle density in sectors, which made it possible to correct crusher performance directly in the calculation process. A method for designing hammer crushers in accordance with the given initial parameters is presented. Keywords Crusher, particle, crushing zone, hammer, impact factor, rotor diameter, mass density.
