“…The company is currently researching intensive vibration effects on the material processed, enabling complete elimination of the use of process water as the disaggregating medium and switching to dry technologies with the application of the so-called vibrational fluidization effect [2][3][4][5][6]. The latter consists in the following: the behavior of a bed of a granular medium under vibration is quite accurately characterized by the overload parameter w that predetermines the occurrence of the vibrational fluidization effect.…”

The research results are presented for the technology to improve the quality of fine powder materials using vibration effects to produce conditioned commercial products meeting the requirements of additive manufacturing and suitable for application in powder metallurgy and mechanical engineering. The effect of vibration fluidization on the separation of fine metal powder with a particle size of less than 40 microns from submicron particles in a non-uniform electric field using a dielectric barrier discharge, which allows to determine the optimal technological parameters of separation, was studied for the first time. The effect of the operating parameters of the ELKOR-1 corona-electrostatic separator on the behavior of fine-dispersed metal powders with a particle size of less than 160 microns in a non-uniform electric field with high intensity, which allows to determine the optimal separation mode with obtaining standard technological parameters, is investigated.
