Title of the articleThe mixing process in the spatial devices
Abstract.Problem statement. Currently, the most promising mixers are spatial with uneven movement of the container, which consists only of rotary joints, designed on standard rolling bearings. Mixers have a high efficiency, one drive source and a minimum number of moving links: three, four, five or six, very effective in operation. While little known, little investigated. The aim of the study is to develop models of volume motion of particles in the tank, to derive mathematical formulas characterizing the conditions of guaranteed slip and separation of particles in different zones of the tank, taking into account the geometric parameters of the mixers and the speed of the tank. Results. The calculation of conditions of sliding and separation of particles from the bottom of the tank at different points of the tank length is given. The mathematical values of the angular velocity of the tank are determined, the influence of the parameters of the transfer mechanism on the conditions of the bulk motion of the material particles is revealed, the optimal modes of the mixing process are determined. Conclusions. The significance of the results for the construction industry is a significant advantage of spatial mixers with uneven movement of the tank for the preparation of highly homogeneous mixtures in composition, versatility of use for many processes, simplicity and reliability.
Keywords.variable angular velocity, acceleration, spatial mixers, rotational hinges, mathematical models.
