To the question of modeling the process of compacting a briquetted material in a pressing plant

Abstract

On the basis of systems thinking, intelligent research methods have been developed for pressing briquette material by constructing a mathematical and computer model of the material compaction process. The apparatus of the installation for studying the process of pressing the material (fine coal fractions) has been developed. The first level of the pressing process deals with the production line for preparing and compacting the material. The second level of the hierarchy includes devices of the technological line, including the device for pressing the material. Starting from the second level of the hierarchy, a material compaction apparatus is considered, in the form of a material compaction plant, where one of the abstract indicators is the material compaction coefficient. The technique of the experiment in the apparatus of the material pressing plant is presented. On the basis of the main parameters of the process of pressing the briquette material revealed during the experiment, a mathematical model was developed in the form of a system of equations. On the basis of the developed mathematical model, the starting characteristic of the material compaction apparatus is studied, which characterizes changes in the relative density of the compressed material. The change in the density of the briquette during the compaction of the material for the installation is equal to 0.25, while the density of the material increases from 600 to 724 kg/m3.
