Electromagnetic vortex intensifier with ferromagnetic particles

Electromagnetic vortex intensifier with ferromagnetic particles (vortex layer devise, electromagnetic mill) consists of an operating chamber (pipeline) with a diameter of 60–330 mm, located inside an inductor with a rotating electromagnetic field. The operating chamber contains cylindrical ferromagnetic particles 0.5–5 mm in diameter and 5–60 mm in length, ranging from tens to several thousand pieces (0.05–20 kg), depending on the dimensions of the operating chamber of the intensifier.
History of electromagnetic vortex intensification.
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:
Following this research, these intensifiers found their application in many researches and developments.
Physical processes in electromagnetic vortex intensifiers.
Intensification of technological processes and chemical reactions is achieved due to intensive mixing and dispersion, acoustic and electromagnetic treatment, high local pressure and electrolysis of processed components. Electromagnetic devices with a vortex layer with ferromagnetic elements accelerate the reactions 1.5-2 times; reduce the consumption of reagents and electricity by 20%. The grinding effect is achieved by the motion of ferromagnetic particles and their free collision with each 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.
Industrial application of electromagnetic vortex intensifiers.
Examples of industrial applications of these devices for intensifying processes are:
Electromagnetic vortex intensifier grinds and regrinds coal, alumina-containing slag, quartz sand, technical diamonds, cellulose, chalk, wood flour, fluoroplastics, etc.
Also, it can be used for decontamination of agricultural animal waste.
