Magnetohydrodynamic Enrichment of Magnetic, Nonmagnetic, Superconducting Particles and the Molten Metals Under Influence of the Sinusoidal, Rotating Magnetic Field
Abstract
The paper presents experimental data on the optimization of Electromagnetic Separation (EMS) as a function of the chemical powder composition, particle dimensions, and magnetic field amplitude. That method permits EM-separation in the magnetic fluids of superconducting (HTSC), magnetic, nonmagnetic particles, and molten mixes in a moving and Rotating Magnetic Field (RMF) generated with the helping of a three-phase linear asynchronous AC motor. This is achieved by the periodic compression and rarefaction in RMF, where is generated of the waves, which appear in the magnetic fluids and moves in the travelling direction of the field. Based on these results, it is shown that the "concentrates" are an enriched mix of magnetic, conducting, or nonmagnetic powders with optimal quality and the "tails" are the recycle fractions requiring additional thermo chemical treatment. EMS may be used as an express method for the evaluation of powder quality and quick correction of synthesis parameters. With a new method developed author in the same time, it was discovered the successful segregation of the molten metals under oscillated and a rotating magnetic field generating by linear form AC-motor.
