Abstract

PURPOSE:To easily carry out classification of fine particles by insulating and crossing each set of filament electrodes to each other, connecting a power source of high voltage and high frequency between the filament electrodes to form an electric field matrix. CONSTITUTION:Electrostatically charged particles are supplied on an electrolytic matrix. In the electrolytic matrix, a power source of high voltage and high frequency is connected between filament electrodes and an electrolysis of high voltage and high frequency is formed. Therefore, a particle 2 having a diameter exceeding a certain diameter oscillates in the shape of an arc and at a high speed on an arcuate electric force line 1, receives centrifugal force in the direction of A2 and is floated by it. A particle 3 smaller than the floating particle 2 is smaller in electrostatic charge than the floating particle 2 and accordingly, generates no sufficient floating force, passes through an electrodynamic pore 4 weak in electrolysis and falls. In this manner, even particles having diameters less than several microns can be easily classified.
