Nonlinear model of the separated mixtures movement in a cylindrical vibrating screen

Abstract

With the use of the hydrodynamic theory, the steady vertical movement of the separated mixture layer on the inner surface of the cylindrical vibrocentrifugal screen that regularly rotates around the vertical axis was described. Power dependence of the tangential shearing stress in the fluid mixture on the velocity derivative of the flow rate of the radial coordinate, borrowed from the theory of viscous non-Newtonian fluid theory, was adopted. The problem of identification of two phenomenological parameters of the fluidized mixture according to measurements of the kinematic characteristics of the flow was explored.
