Due to difficulties in determination of a blend quality in industrial conditions using conventional methods there are needs of finding out brand-new solutions providing quick and precise estimation of a mixing degree M at certain stage of a mixing. One of these methods can be a computer picture analysis of the crosswise profile of a bin fulfilled by the two-component granular blend. Based on the laboratory mixing device, containing from the two the same bins, the usefulness and effectiveness of this method was presented to evaluate the mixed bed quality. The snapshots of the crosswise profiles provide estimation of the mixing degree at certain stage of a mixing. The achieved parameters were compared statistically with the parameters obtained using classical sieve analysis. The obtained mixing parameters expressed in the M degrees versus the process steps were presented graphically in the scatterplots (Figures 4, 5). Next, the photographic results with those achieved using the classical sieve method were compared statistically. The results were satisfing.
