| Research Abstract |
The high quantity of plastic waste produced has resulted in a lack of suitable sites for landfilling. In view of the environmental problems, it is desirable that the performance of plastic recycling systems is improved so as to reduce disposal.
Plastic products usually consist of different materials such as nonferrous metal and plastic. Therefore, the separation is one of the most important processes in a plastics recycling system. There are many separation methods of nonferrous metal -plastic mixture such as density based separation and electric conductivity-based separation. Although many studies have demonstrated the effectiveness of the separators, these investigations have not yet been completed. The further development of a novel separation method with high separation efficiency is required.
This paper presents the results of experimental and analytical studies of the performance of a novel electrostatic separator. The separator consists of a vibratory conveyor equipped with two plate electrodes. The mixture is charged by following methods : ion bombardment (corona), induction and triboelectric charging. The separation tests were performed on a sample containing 50% polyvinylchloride (PVC) and 50% copper. This study was conducted to understand the effects of the various parameters on the separation efficiency, in order to obtain the optimum operating conditions.
