Abstract

Optimal oscillation parameters of vibrating screens are determined using analytical methods by investigating movement of a single spherical grain particle in the vibrating sieve’s non-inertial reference frame. Dimensionless parameters determining the efficiency of screening process are defined. Effect of interactions between multiple numbers of particles moving on the screen is analyzed using discrete element method. By comparing the analytical and numerical results, it can be seen, that the analytical evaluation of screening efficiency can be used until a given contaminant size unlimitedly in the examined range of screen angle. Additionally in case of this minimal contaminant size there is a maximal screening angle value. Above this angle it seems, that the use of our discrete element based evaluation of screening efficiency is unavoidable.
