The bulk materials movement analysis at the bunkers outlet

Purpose. The study of the bulk material physics and mechanical properties influence on the its movement nature at the bunker outlet. Methodology. We used the mathematical modeling and regression analysis methods. Findings. The characteristic features of the material main movement modes (normal and hydraulic) are defined. Mathematical models of the bulk materials movement in conical-cylindrical bunkers are given, the bunker and particles parameters influence on their velocity is analyzed. An equipment was developed and experimental studies of the materials discharge rate from bunkers were carried out, the results are presented in the work. Originality. Mathematical models of the bulk materials movement in conical and cylindrical bunkers are obtained. The dependences between the particles physic-mechanical parameters and their movement speed are established. Practical value. The results obtained allow us to predict the bunker equipment performance of for various bulk materials types
