The comparative data of energy intensity of various grinding devices including devices with a vortex layer are presented. It is established that the energy intensity of devices with a vortex layer is higher by several orders than in the working zone of mills of different types. The dependence of the size of ferromagnetic particles in the working chamber of the apparatus with a vortex layer on the critical filling factor of the working chamber is determined. The method of calculating the optimal configuration of the stationary magnetic field pattern in the working area of devices with a vortex layer is determined. It is revealed that from the point of application of the method of equivalent magnetic charges in the apparatus of vortex layer the most rational is the variant with sinusoidal distribution of magnetic potentials at рп=1. At the same time, a uniform movement of ferromagnetic elements inside the cylindrical magnetic circuit can be ensured.
