A basic research is being carried out on the transport of particles and the particle size classification in the electrostatic traveling field. A particle conveyor consisting of parallel electrodes was constructed and four-phase traveling electrostatic wave was applied to the electrodes to transport particles on the conveyor. The following were clarified by the investigation : (l) The direction of the particle transport did not always coincide with that of the traveling wave but partially changed depending on the frequency of the wave, the particle diameter, and the electric field.(2) Particles were classified with size under the voltage application of appropriate frequency.
