Petrenko D. Parametres ground of centrifugal-pneumatic grain separator

Research subject - process of division of grain mixtures on aerodynamic factors in the action field of inertia forces of centrifugal-pneumatic separator. Research object - increase of air division productivity of grain mixtures by grounding of parameters of centrifugal-pneumatic separator. Research methods. Theoretical researches are executed with the use of elements of theoretical mechanics, differential and integral calculation and mathematical design. Experimental research results are treated with application of elements of probability theory and mathematical statistics. The rational parameters of the improved centrifugal-pneumatic separator with rod surface cylindrical drum have been grounded for the first time by means of analytic determination; the mathematical analysis of grain material movement mechanism in air channel through the rod surface of active drum subject to environment resistance has been developed; it has been worked out the mathematical model that allows to define process energy intensity of grain material movement through the surface of cylindrical drum with rod surface in action field of airflow; it has been experimentally got the influence factors of basic structural parameters of centrifugal-pneumatic separator on the high-quality, technological and operating indexes of its work. The elements of separator construction are protected by the patent of Ukraine on inventions. Designer documentation on making the experimental model has been worked out and sent to several enterprises of Kirovograd to be produced. Experimental unit "Centrifugal-pneumatic separator" is used in training process.
