Experimental studies of energy characteristics of mixer with deformable camera

Mixing bulk materials is widespread in various industries: construction, agro-industrial complex, chemical technology, energy industry and many others. At the same time, the task of preparing homogeneous mixtures is associated with a number of difficulties, such as a wide range of changes in the physicomechanical properties of the processed materials, requirements for the quality and composition of the product, productivity, energy and metal consumption, etc.

The aim of the research was to increase the efficiency of the modernized (by replacing the blades) transportable drum mixer by intensifying the mixing stroke by improving its design and optimizing the mixing time of the components. The research methodology provided for a regression analysis of experimental results to establish the function of the influence of the mixing duration on the coefficient of variation. The best quality of the mixture is observed in the mixing time interval of 60-300 sec, with an optimum of about 120-140 sec. The average value of the coefficient of variation in this case corresponded to 10.9%. Due to the inconsistency of the results of a one-stage mixing with technological requirements for the quality of the mixture, the function for a two-stage mixing is justified. The optimum ratio of the pre-mix filler to the control component is about 4. The mixing time of the second mixing stage should correspond to 180 seconds. Moreover, the unevenness of the mixture (10%) meets the technological requirements. Compared to the typical design of the mixer used, a 7% improvement in the quality of the mixture is observed.
