Development of the continuous frictional charging method for the electrostatic waste plastics separator

Abstract

We have already developed the electrostatic separator which utilizes characteristics of electrification caused by friction of plastics to recycle waste plastics. The electrostatic separator is composed of a separating part and a device of frictional electrification which stirs and equally electrifies plastics for a fixed time by batch process. Therefore, repeating the batch process with more stirrers are needed for continuous process. This report introduces an outline of a compact device of continuous frictional electrification which makes friction between plastics continuously and electrifies them. It also describes the examination performance of the electrostatic separator with the continuous frictional electrification
