The experimental research results of the mixture quality in the vibration mixer with a profile bottom depending on the process life, mixer bottom geometry, and vibration parameters (amplitude and frequency of fluctuations) are presented. The technique for continuous determining the mixture quality in time is offered for investigating the process of vibratory mixing model material at the pilot unit using the video shooting, and with the footage postprocessing. The applicability domain of the offered research method of the vibration mixing process is defined. The heterogeneity coefficient is accepted as a criterion of the mixture quality assessment. Particular attention is paid to the statistical analysis of the experimental data. The experiment results are visualized and presented in the form of the mathematical relation of the mixture heterogeneity coefficient and the process life. The theoretical solutions about the dependence of the mixture quality on the mixing time are confirmed experimentally.
