When developing an inductor for these devices, the salient-pole design of liquid steel induction rotators was chosen as an analogue. The choice of salient-pole inductor design was associated mainly with simplified manufacturing technology, ease of operation, repair and cooling.

other, and a constrained collision between the particles and a body. The degree of grinding is 0.5 μm (with an initial size of 20 mm). At present, the electromagnetic devices with a vortex layer with ferromagnetic elements actually exist (D.D. Logvinenko himself designed and produced more than 2000 pieces), their principle is also implemented in some technological lines.

The grinding effect is achieved by the motion of ferromagnetic particles and their free collision with each

Subsequently, the line of these and similar devices was mastered, modified and expanded by other manufacturers and developers. Currently, devices use both salient-pole inductors and inductors with distributed windings, similar to the stators of electric motors; different types of cooling, different

In the central part of the working area of these devices, the magnetic field in the absence of ferromagnetic particles is close to uniform: the hodograph of the magnetic induction vector in this area is close to a circle, coinciding with it in the center of the working area of these devices; the

Electromagnetic devices with a vortex layer were proposed in 1967 by D.D. Logvinenko and O.P. Shelyakov. The monograph "intensification of technological processes on devices with a vortex layer", written by these authors, showed the effective use of these devices in:

The devices have dual-circuit oil-water cooling, power capacitors to compensate for the reactive power of the inductor and are powered from a 380V, 50 Hz network. Other design features of the devices are described in detail in the monograph.
