MODEL OF THE QUALITY-POWER INDICATOR OF A ROTARY DRUM MIXER

Abstract

Based on experimental studies, the article presents the issues of improving the quality indicators of the drum feed mixer, describes its design and operating principle. The research was conducted in accordance with the current methodology and materials presented in the article. Based on the results of approximation of the initially calculated values of the quality-power indicator, a statistical model of this quality-power indicator (0.01% kW) is obtained. The value of errors in the calculated data is ana-lyzed for correspondence with the initial data. After processing the obtained experimental data, the description of dependence diagrams on the influence of the design parameters of the working body of the drum mixer on the quality and power indicator is shown. An increase in the height of the instal-lation of blades is undesirable over 0.16 m, and an increase in the number of blades over eight leads to a rapid deterioration in the quantity-power indicator. The relevant conclusions on the application of the studied design and operating parameters in the working of the drum mixer are presented.
