Phenomenological Model of Abrasive Tool Components Mixing Process

The article considers the peculiarities of the process of mixing the abrasive grains with the particles of ceramic binder and adhesion-neutral filler for the manufacture of abrasive tools. We determined the conditions for the uniform distribution of the binder in the molding compound and the aggregation of these components during their mixing, in which abrasive grains become structure-forming. We got the formula for the analytical determination of the mixing uniformity ratio considering the mixing mode, the volume content of the components, and the void ratio of mixture. The implemented theoretical and experimental investigations and the basis of the phenomenological model allowed substantiating the character of the processes, as well as analytically determining, using the derived dependencies, the conditions for the uniform distribution of the components of molding mixtures for the production of heavy-duty abrasive tools.
