A mathematical model of the process of classification of granular materials using vibration screens is proposed by the authors. The objective of the modeling process is to describe the kinetics of extraction of granules sieved through upper and bottom sieves. The proposed model takes account of the pattern of diffusion and segregation of particles migrating through vibration screens. The model is based on the cell presentation of the process. The matrix of transition probabilities controls the particle distribution over each screen sieve. Sieved fractions are described separately, and successful sieving depends on the probability of a fraction to get through the sieve cell in the course of one sieving attempt. This probability depends on the ratio of the particle size to the sieve cell dimensions as well as on the screen oscillation parameters. The model may be used to calculate the kinetics of sieved fractions if the pre-set feed rate of particles, particles size distribution and velocity of their motion over the sieve surface are available.
