The possible reserve to enhance the vibration mixing process efficiency
The purpose of the research is to study the possibilities of increasing the efficiency of the process of vibration mixing in the preparation of feed mixtures for chickens. The work was carried out in LLC Borodino-Orenburg, the enterprise Fermerstroyservis - Orenburg Region. The object of research was the process of mixing bulk feed in a vibrating mixer using stimulating vibroactive surfaces. Materials and research methods. Mathematical methods for predicting the results of the vibration mixing process allow finding reserves for increasing its efficiency. Accordingly, the selected model of the behavior of bulk ingredients during vibration allows you to create the structure of a mathematical model of the technological process that most accurately reflects it. The mathematical model is formed on the basis of the dominant process indicators and is a system that includes a combination of: various modes of operation of mixing devices, methodological and technical support of the elements of mixture preparation, the creation of a constructive-geometric working space of the vibratory mixer with elements of the internal working vibroactive surfaces. In many ways, the potential for increasing the efficiency of the vibration mixing process depends on the choice of mixing equipment. Research results. In the course of the experimental studies, various interchangeable vibroactive surfaces were used, which were placed stationary in the center of the mixer body, which differed in the sizes of the areas and the shape configuration. It was found that when preparing feed mixtures with a humidity of up to 15 %, for young chickens, the mixture turns out to be 1.1 - 1.55 % higher in uniformity if vibroactive surfaces of complex configuration are used. A possible reserve for increasing the efficiency of the vibration mixing process is determined by: developing methodological and technical support for the elements of mixing, selecting a model of behavior of a granular medium for mathematical description and predicting high-quality energy results, and forming a constructive working space for mixing devices.
