text: 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:
  * mixing of liquids and gases
  * mixing of loose materials
  * dry grinding of solids (micro-resin)
  * grinding and dispersion of solids in liquid media
  * activation of substance surface
  * implementation of chemical reactions
  * changes in the physical and chemical properties of substances
  Following this research, these intensifiers found their application in many researches and developments.
