PROJECT TITLE :
Tribo-Aero-Electrostatic Separator for Ternary Mixtures of Granular Plastics
This paper presents a comprehensive study of an electrostatic separation device for the recycling of granular plastic materials from waste electrical and electronic equipment (WEEE). The peculiarity of this technique is the association of 2 charging techniques: one) fluidized bed (dynamic charger) and a couple of) sliding on inclined plates (static charger)—and 2 superposed separation units, so as to realize the selective sorting of a granular mixture composed of 3 completely different species of insulating materials. The tests were performed on a combination of high-density polyethylene (HDPE), polyvinyl chloride (PVC), and polycarbonate (PC). A collection of tribocharging experiments was conducted for each material, so that to decide on the character of the walls of the static charger. The analysis of the purity of separated merchandise was performed using a picture processing program written in MATLAB. High-purity separation (85p.c, 95percent, and 75p.c for the PVC, PC, and HDPE products, respectively) was obtained at a recovery rate beyond eightypercent.
