The installation works as follows.

From tank 4 by pump 2, which operates at a constant capacity, the initial mixture of chocolate mass through line 3 is poured into a ball mill 1.

The ground mass that is crushed in mill 1 is discharged through the discharge pipe.

When the mill 1 is operating at the optimal mode, which ensures that the finished mass of the desired dispersion is obtained, the additional pump 5 operates at its minimum capacity. When the pump 5 is operated from the upper part of the mill 1, the mass through the pipeline 1 1 is supplied to the tank 4. At the same time, the ultrasonic oscillator 8, configured to operate in a pulsed mode, every 30 seconds delivers a series of electrical sinusoidal oscillations with a certain frequency, for example 25kG c, on the coil of the ultrasonic vibrator 7.

Ultrasonic waves propagating in the chocolate mass flowing through conduit 11 reach the piezoelectric element 10 of the receiver 9 of ultrasonic vibrations and cause its compression and relaxation, as a result of which the electric potential difference appears at the poles of the element 10. An electrical signal arising from a potential difference is applied through the oscillation receiver 9 to the comparison unit 19, and from it the signal propagates in two directions for

generating control signals for the installation.

From block 19, signals are sent to systems 14 and 15, where control signals are generated, respectively, directed to control the drive of the mill and to control the operation of electromagnets 12 and 13. Signals from receiver 9 go to block 19. In the normal course of the grinding process, when grinding to the required dispersion takes place, block 19 does not give a signal for choke154

threads 14 and 15 automatic control.

In case of a change in the dispersed composition, block 19 generates a signal and sends it in parallel to the systems

14 and 15.

When a signal arrives in the system

The electromagnets 12 and 13 located on the housing create a pulsed magnetic field that spreads to the working volume of mill 1 filled with ferromagnetic spherical elements. The effect of this floor on the balls leads both to an increase in the force interaction between them, and to an increase in their interaction with the mill body 1.
