- W4308589344 abstract "One of the undesirable factors when grinding grain with hammer crushers is the formation of flour dust, which is fire and explosive, as well as harmful to the health of service personnel. The applied fabric dust collectors ineffectively purify the air coming out of the pneumatic system of the crusher. One of the directions of development of dust collection equipment is the development of wet dust collectors or the improvement of existing ones. The proposed two-stage wet dust collector gives greater efficiency of air purification from dust, which is shown by laboratory studies. One of the factors affecting the quality of cleaning is the speed of rotation of the agitator blade, which varies depending on the concentration of dust in the liquid of the first stage. Not the entire dust-air mixture passes through the upgraded dust collector, but only the part that is redundant. This allows you to increase the life of the dust collector before the next service. The aim of the work is to study the dependence of the rotation speed of the blade of the agitator of the first stage of the dust collector on the density of the liquid. Methods of mathematical modeling of the agitator operation, approximation and regression analysis were used for the research, correlation analysis was performed. Theoretical studies have revealed a hyperbolic dependence of the rotation frequency of the paddle agitator on the density of the colloidal solution, however, experimental data provided other quantitative indicators. To determine the necessary parameters of the equation, the least squares method was used to approximate the experimental data. The calculated data obtained were compared with the experimental ones by the coefficient of determination, and the model was highly adequate, R2 = 0,9705. The presented method of selecting the regression equation shows good convergence with the experiment. The equations derived for a laboratory installation can be converted to an industrial design using the theory of similarity." @default.
