The relevance of the use of low-volume rotary disk mixers

In the presented work, a description of the principle of operation of a rotary-disk mixer is given. The author notes that in industry the designs of a rotary-disk mixer with smooth disks having additional elements rigidly fixed in the form of blades or teeth of various shapes are most widely used in industry. The description of 4 developed constructions of working disks with structural differences is given. An experimental proof of the effectiveness of the use of additional working bodies is given. It is noted that the latter lead to the emergence of new highly turbulent flows of the processed medium, which has a positive effect on the processes of emulsification and dispersion. It is shown that with an increase in the proportion of the dispersed phase in a stirred medium, the average size of the droplets of the dispersed phase increases. This is explained by an increase in the concentration of the dispersed phase and the frequency of collisions of droplets of dispersed particles, which lead to coalescence. It has been established that the size of the particles of the dispersed phase decreases inversely with the rotor speed and the increase in the dissipation energy.
