Hybrid fuzzy kinetic model of phosphorite pellets drying process

Abstract

Abstract The chemical-technological process of phosphate pellets drying is investigated in the paper. The hybrid fuzzy kinetic model of phosphorite pellets drying process is proposed. The features of the proposed model are as follows: firstly, differential equations with fuzzy thermal-physical characteristics of pellets are used to estimate the thermal conductivity of pellets; secondly, a fuzzy rule-based model is used to determine the most difficult parameters to calculate. The method based on the developed hybrid model is proposed for analyzing the drying process of phosphorite pellets. The proposed method uses an original approach that allows solving the problem of increasing uncertainty of results in iterative calculations based on the modal interaction of fuzzy thermal characteristics represented by fuzzy numbers.
