Studies of the Influence of the Planetary Mixer Design and Technological Parameters on the Quality of Mixtures

The involvement of secondary material resources in production is an urgent task, as it is aimed not only at solving environmental problems, but also makes it possible to reduce the cost of extraction and processing of raw materials. The paper studies the possibility of using waste in the road sector as components of anti-icing mixtures for winter maintenance of roads. The influence of design and technological parameters of a planetary mixer on the process of producing anti-icing mixture based on sand, salt and anhydrous calcium chloride formed as a by-product in the production of soda and Potassium chlorate has been studied. To conduct experimental studies, well-known methods for determining the quality of mixtures by the coefficient of heterogeneity were used. The regularities of material movement in the volumetric-spatial contour of the working chamber are established. The graphical dependences of the effect of the mixing duration and the rotor rotation frequency of the mixer on the coefficient of heterogeneity were plotted. The research results show that the developed mixer improves the quality of the mixture due to a more uniform distribution of components throughout the useful volume of the mixing chamber, and the resulting reagent can be used as a friction anti-icing material for road treatment in the winter season.
