Математические модели обогащения для автоматизированных систем управления качеством дешламации магнетита

Abstract

The article deals with construction of mathematical models of the process of magnetite desliming. Built models should be suitable for use in automated systems for process control. The results of the study are models of the motion of two-phase slurry in the case of an axisymmetric two-dimensional and three-dimensional vortex flow of the pulp. To calculate the three-dimensional flow and particle trajectories the applications Flow Simulation was used from package SolidWorks. We also developed a method of imitating the numerical experiment to determine the dependence of the enrichment's quality from the process parameters and the shape of the desliming machine. The results of calculations allow us to estimate the impact of technological and structural factors on the quality of the magnetite enrichment. The practical value of the results is the possibility of direct use of models in the automated control systems enrichment processes.
