dc.description.abstractIntroduction. Analytical and experimental research was conducted to improve the process and equipment for the superfine grinding of medicinal and cosmetic preparations. Materials and methods. On the basis of modern scientific literature and own experience was given a comparative analysis of modern equipment for ultra-fine grinding. In the investigation are used suspensions of titanium dioxide and quinacridone red 122 with the vaseline oil. Results and discussion. Among the recommended installations, the most versatile, productive, compact, energy saving, with high degree for grinding (up to 1 microns), effective in the process of dispersion and homogenization, have a simple constructive solution are bead mills. When grinding titanium dioxide over a period of 0 to 30 minutes, the power increases from 205 to 209 W. The temperature of the suspension is from 21.9 to 23.4 °C, the density increases from 889 to 1176 kg/m3, and the particle size decreases from more than 100 μm to 10 μm. The most intensive grinding in the first 5 minutes of the process. When the quinacridone red 122 is grinded, the power is increased from 205 to 210 W, the temperature of the suspension is from 22.4 to 24.3 °C, the density increases from 870 to 952 kg/m3, and the particle size decreases from more than 60 μm to 2 μm, while the most intensive grinding occurs in the first 5 minutes of the process. Conclusions. Among the recommended installations, the most optimal and productive are bead mills. It is recommended to carry out the grinding process on the bead mills periodically with the circulation of the suspension with the obligatory cooling.uk_UA
