Determination of lateral pressure coefficient for friable material in closed vessel
Abstract: The author’s theoretical model for determination of lateral pressure coefficient of friable ma-terial on the closed vessel walls is diven in this article. The model represents 3-d space dis-crete system, which permits to take into account the most significant peculiarities of internal structure of the friable material. The distinction of the existent models from the other models has been shown. By means of the worked out model the author has obtained for calculation of the lateral pres-sure coefficient in a closed vessel. It was shown, that the coefficient depends on not only a row of physical and mechanical characteristics of the friable material, but also on the geomet-rical parameters of the vessel. Hypothesis made by the author as for the changing of the structure of friable material during its movement in the closed vessel allowed to obtain the special theoretical expression for the lateral pressure coefficient in the moment of discharge beginning. Its value is higher than for the analogous coefficient for the static state of material.
Keywords: friable material, capacity, pressure of friable material.
