Coefficient of local loss of mechanical energy of the flow for a ­mixture of charge materials

Purpose. To determine the dependence of coefficient local losses mechanical energy flow a two-component mixture charge material on its depth, content components, and average equivalent diameter particles in case their free-dispersed motion. Methodology. The value was determined by hydraulic resistance fluid during movement open channels pipes. In this paper, methods were used comparative analysis, mathematical modeling forecasting dynamic processes granular material. Findings. Based results theoretical studies, model obtained, use which allows calculating for materials with agglomerate particle sizes from 15 to 50 mm, pellets 6 12 coke 10 60 mm. developed satisfactory accuracy makes it possible evaluate indicated along paths charging devices blast furnaces at speed range 1.5 20 m/s trajectories top an 0.2 m. It is noted that calculation above known techniques not accurate enough, associated uncertainty choice single charge. Comparative analysis models experimental data indicates parameters using increases 510% comparison calculations previously models. Originality. For first time, regularities changes internal diameters when moving have been established. Practical value. Mathematical dependencies can be technological modern furnace different characteristics granulometry ratios components. This will increase predicting course process under consideration, degree automation control systems supply furnaces, make expensive more efficiently, reduce consumption harmful impact environment.
