MODELING OF VIBRATION SEPARATION OF BULK MATERIALS BASED ON THE THEORY OF RANDOM PROCESSES
The process of vibrational separation of bulk materials into specific fractions by size on multilevel sieve classifiers was studied taking into account the stochastic nature of such processes. As a random process, the linear particle density of the considered fractions on the sieve surface is considered and the system of stochastic differential equations is constructed for its determination. The solution of the system of stochastic differential equations is obtained and the numerical characteristics of the random process are determined. The obtained solutions made it possible to calculate the extraction coefficient and evaluate the separation efficiency.
