dc.description.abstractThe process of ultrafine grinding of components of medicines and cosmetics in a laboratory bead mill is considered. The purpose of the study is (1) to determine the energy parameters of the process of ultrafine grinding of medicinal and cosmetic components in a bead mill, as well as (2) to determine the dependences of changes in technological parameters. A suspension of castor oil and cosmetic pigment in a ratio of 60% oil and 40% pigment was used as a model body. A series of experiments was carried out, where the degree of grinding was determined using a microscope with a built-in camera and software, the temperature was measured with ds18b20 temperature sensors, the power was measured with a three-phase CNFAJ Intelligent Power Meter. When grinding the pigment "red 120" for a period of time from 0 to 45 minutes, the power decreases, the temperature of the "beads-product" system increases, and the particle size decreases. This process occurs most intensively in the first 5 minutes. Most of the energy is spent on the work, which is spent on mixing the system "beads-product", and the work, that is spent on heating the structural components of the product and the parts of the mill interacting with them, which, in turn, depend on rheological properties of the suspension.uk_UA
