| Popis: | The process of separation of granular materials into specific size fractions on sieve classifiers based on Poisson processes that relate to discontinuous Markov processes with discrete states is studied. The residence of particles of a certain size fraction on the surface of the sieves is defined as certain states, and a transition point from one state to another state (sieving) is defined as a random process. To determine the probabilities of states, a system of stochastic differential equations is constructed, the coefficients of which are calculated as dependent on the probability of sifting the particles into sieve cells. The solutions allow one to calculate the extraction rate and evaluate the separation efficiency. A computational experiment is conducted to study the main characteristics of the process. |
