The disadvantage of this device for grinding products is the design complexity and low productivity of the device due to the small grinding zone and processing environment.

The closest technical solution to the proposed utility model (prototype) is a centrifugal mill containing a cylindrical body, mounted in it fixed disk partitions and a vertically located working body, loading and unloading bins, drive, disk partitions made perforated and working body - in the form of rotating perforated discs located between fixed disk partitions. [A.S. USSR No. 715134, cl. B 02 C 7/08, Centrifugal Mill / Voskanyan R.A .; Stated on 11.25.77 .; Posted 02/15/1980.]

The disadvantage of this centrifugal mill is the relatively low efficiency for grinding and mixing heterogeneous liquid-liquid systems, liquid-solid particles.

The proposed utility model solves the problem of increasing the efficiency and productivity of the process of grinding and mixing heterogeneous liquid-liquid systems, liquid-solid particles.

This problem is solved due to the fact that the rotary disintegrator - mixer contains loading and unloading nozzles, a drive, a fixed cylindrical body, in the volume of which perforated disks are rigidly fixed, located alternately with similar perforated disks fixed in design, mounted on a rotating rotor, according to a utility model, holes of perforated discs mounted on a rotating rotor are oriented at an angle of 45 °

direction from the center to the periphery, and the holes of the rigidly fixed perforated discs - in the direction from the periphery to the center.

Also, the gap between the rotating and fixed disks can be adjusted by moving the rotor in the vertical direction by rotating the adjusting nut, and the ratio of the geometric dimensions of the hole diameter and the thickness of the disk is in the range of 1 ÷ 1.5.

Figure 1 shows a rotary disintegrator - mixer.

Figure 2 shows a perforated disc.

The rotary disintegrator - mixer contains a boot 1 and a discharge 2 nozzles, a drive, a fixed cylindrical body 3, in the volume of which perforated disks 4 are rigidly fixed, located alternately with similar perforated disks of a design fixed to a rotating rotor, and the holes of the perforated disks fixed to rotating rotor, oriented at an angle of 45 ° in the direction from the center to the periphery, and the holes of the rigidly fixed perforated discs - in the direction from the periphery to the center.

Also, the gap between the rotating and fixed disks can be adjusted by moving the rotor in the vertical direction by rotating the adjusting nut 5, and the ratio

the geometrical dimensions of the diameter of the hole and the thickness of the disk is in the range of 1 ÷ 1.5.

Rotary disintegrator - mixer operates as follows.

Under the action of mass forces or artificially generated excess pressure, the heterogeneous medium being processed is moved from the loading pipe 1 to the discharge pipe 2. When moving through the perforated disks 4, the heterogeneous medium is subjected to intense mechanical stress and grinding and mixing process.

The intensity of the mechanical action is achieved by a relatively high rotor speed and the highly turbulent movement of the medium being processed in the gaps between the rotating and stationary perforated disks 4 and due to the forced blocking of the flow channels of the medium being processed with the occurrence of significant values of the velocity and pressure gradient.

The selected value of the intervals of the ratio of the diameter of the hole to the thickness of the disk equal to 1 ÷ 1.5, according to the results obtained as a result of experiments, ensures the most efficient operation of the apparatus.

The orientation of the holes of the rotating perforated disks at an angle of 45 ° from the center to the periphery and the holes of the rigidly fixed perforated disks at an angle of 45 ° in the direction from the periphery to the center, was chosen for reasons of providing a longer hydrodynamic effect on the medium being processed during operation of the apparatus,

as well as to equalize the pressure difference in the volume of the apparatus, resulting from the appearance of centrifugal force during rotation of the rotor of the apparatus.

The ability to change the gap between the rotating and fixed disks by moving the rotor in the vertical direction by rotating the adjusting nut, allows to obtain dispersed particles of the required size at the outlet of the apparatus.

The main advantages of the proposed design of a rotary disintegrator - mixer include the following:

- multifunctionality, which is caused by the possibility of grinding and mixing heterogeneous liquid-liquid systems, liquid-solid particles;

- the ability to control the intensity of the mechanical impact on the crushed and mixed medium by changing the gap between the rotating and stationary disks by moving the rotor in the vertical direction by rotating the adjusting nut;

- high productivity and efficiency of the grinding and mixing process.

The invention meets the criterion of "industrial applicability" and can be used in the chemical, food and paint industry for grinding and mixing heterogeneous liquid-liquid systems, liquid-solid particles.
