LIQUIDS EMULSIFICATION IN ROTARY DISC MIXERS
There are the results of emulsification process experimental researches carried in rotor-disc mixers, which contain movable and unmovable discs with perforation and additional elements as the teeth. The processed mixture passing through the equipment work capacity is subjected to the intensive mechanical and hydro-dynamical influenced by the working tools side. A water and the diesel fuel in various proportions were used as the etalon liquids. It is established that the dimensionless parameter proportional to discs surfaces area is the common criterion, which characterized efficiency of device work. The dependence of dispersed particles characteristic size on the dissipated power and constructive parameters of mixers is determined. The Ronald criterion, in which characteristic size is adopted as the relation of total area of perforation surface of rotating disc to disc diameter, is adopted as the efficiency criterion of energy transfer from the rotating disc to the processed area. There is showed that in increase Ronald criterion the dispersed particles characteristic size is reduce ~Re-3/2 but in this the particles sizes scatter is reduce by sizes. There is follows from a given experiments that the form of dispersed particles distribution by sizes is change by the changing the construction of equipment working elements and the rotor rotation speed and consequently the area of interphase surface of the processed liquids.
