Abstract: The results of experimental research of processes of emulsification in liquid-liquid systems in rotor-disk mixers with various designs of working bodies allowing to regulate the disperse particles size distribution are presented. It is shown that increased area of perforations on the working parts of the rotary disc mixer and installation of additional elements (teeth) reduce the total size of the dispersed particles. At the same time, the consumed power is increased because for the same experimental parameters (rotation speed, flow rate, mixing ratio), the average size of dispersed particles decreases and, consequently, the area of the interfacial surface increases
