Abstract
This article discusses perspective directions of development of pneumatic mixers for mixing dry building mixes. Pneumatic mixers are modern equipment used for mixing dry building materials and fine materials that meet the requirements for environmental and industrial standards that surpass mechanical mixing units in their technical characteristics and do not harm the health of operators. Mixing materials with high-intensity movement of particles through the mixing chamber and with other material particles allows for obtaining a finished mixture with a high percentage of uniformity, which allows increasing the quality characteristics of the finished product, which is of no small importance in the manufacture of building materials. In this article, we present a new patented design of a pneumatic mixer, the distinctive quality of which it improves the properties of the final product and high uniformity of the finished mixture due to intensification of the mixing process. The method for calculating the process of mixing the components of bulk material in a pneumatic mixer is provided. According to the results which we obtained, the ratio that determines the change in the concentration of a selected component of bulk materials in the cylindrical volume of the mixing chamber. The results of this article can be used in the design of pneumatic mixers for mixing dry building mixtures.
