Abstract

The article contains a mathematical description of the process of mixing bulk materials in a drum aggregate using elements of mathematical statistics, theory of probability and averaging models. A random stationary process is a flow that is formed by means of dispensers in this case. The correlation function is used as its parameter. It is a measure of the stability of the process. The relationship between the variances of the input and output signals is established by means of a correlation analysis. It allows predicting the degree of homogeneity of the material flow (smoothing ability of the mixer) at the output for the given parameters of the input signal: the coefficients of recycling, the time of its presence in the mixer and the dispersion of the input signal. The correlation analysis of the flow of material allowed the development of a new design of a continuous drum mixer. As a result, we found that the organization of external and internal recycling circuits greatly affects the reduction of fluctuations in the input signal. This reduces the variance of components and increases homogeneity of the mixture.
