Abstract
In different industries, separation (classification) is a typical process in processing bulk and granular materials. The mathematical model of the separation process based on theoretical mechanics and Markov chains’ theory was proposed. The model allows us to consider the sieve parameters, such as the tilt angle, the pitch and size of sieve orifices, and the material particles’ parameters such as size, friction coefficient, and initial velocity. Modeling the separation process allows us to justify the sieve parameters when the sieve is used effectively. The research methodology involved a comparison between model predictions and experimental data. The bulk material separation process’s intensity index on the sieve was calculated based on the experimental study results. Comparison between model data and experimental data indicates the adequacy of the proposed mathematical model of the separation process. The separator’s design elements are also offered, which will ensure the separation process’s high efficiency.
