A preliminary experiment was conducted to classify particle size from mixed particles utilizing electrostatic force. An experimental setup was composed of two parts. One was a parallel electrode array which transported particles by virtue of the electrostatic traveling wave and another was a charged separation roller located on the upper side of the array. It was demonstrated that particles were charged on the parallel electrodes and small particles were attached to the separation roller, when the traveling electrostatic wave was applied to the parallel electrode.
