Separation of Fine Particles with the Set Dimensional and Physical Characteristics by Method of the Crown Separation

Abstract:

In this scientific work the new method of electroseparation by means of impact on a dust fraction of the crown charge is considered. The presented device for the electromechanical separation is the main competitor for systems of the electrostatic, crown, dielectric, triboadhesion separation widespread in the industry today. Use of the electromechanical device for crown separation allows separation of fine particles with the set dimensional and physical characteristics from the stream. The main attention in the article is paid to the research of a fine fraction behaviour in the non-uniform electric field. Mechanisms of the impact of electric, gravitational, aerodynamic and other disturbances on the dust fraction (aerosols) are considered in detail. The system of the equations describing physical processes of the movement of a dust particle in the non-uniform electric field taking into account influence of the aerodynamic effort created by the "ionic" wind is presented in this work.
