The article presents the study results of quality (coefficient of heterogeneity) of obtained dispersed mixtures of hard-to-separate materials of I-III fluidity class by the Kerr method with components ratio 1:10 or more. On laboratory gravitational unit implements a patented three-stage mixing method that adhesion and segregation effects minimizes on homogeneity. The quality indicator was calculated using a contactless method, which is also an object of intellectual property. The feasibility of using the three -stage method in construction and other areas is justified by minimal values of heterogeneity coefficient obtained in experiment (Vc=6.1%) for rational ranges of laboratory mixer controlled parameters. A comparison is made with a more energy -consuming four-stage method of mixing components 1:10 (or more).
