Mathematical modeling of thin-layer separation of granular materials on sieve classifiers

A mathematical model of the kinetics of the thin-layer separation of granular materials on multiple-deck sieve classifiers was constructed based on the theory of Markovian processes. To derive the kinetic equations, we calculated the probability of sieving into a mesh depending on the shape and size of sieve holes and separated material granules taking into consideration the effect of the relative velocity of their motion. Using the oversize residues from sieves, we identified the kinetic models, performed numerical calculations, and determined the efficiency of separation.
