Kharchenko S. Conception of intensification of processes of the vibrosieve sifting of grain mixes

The thesis is devoted to solution of current scientific and practical problem of increase in productivity of vibrosieve sifting of grain mixes. The offered concept of intensification of sifting processes on vibrosieves based on hydrodynamic analogy of movement grain mixes to movement of vesiculate fluidized medium and use of activators. Created mathematical models of dynamics of process on flat and cylindrical vibrosieves which take into account the parameters of openings and activators and properties of grain mixtures. The developed vibrosieves with epicycloid volumetric activators have passed fail-safe tests and introduced into the mass production and complete set of vibrating grain separators. Productivity of vibrating separators increased by on 23,8...95%.
