Materials used in the tests. The plastics mixture used in the initial study of tribo-electrostatic separation consisted of PP and HDPE. These were chosen because of the difficulty involved in separating them. PP has a density of 0.9–0.91 g/cm 3, while HDPE has a density of 0.94–0.97 g/cm 3.
The belt is made of plastic material. The separator electrode length is approximately 6 meters (20 ft.) and the width 1.25 meters (4 ft.) for full size commercial units. The power consumption is about 1 kilowatt-hour per tonne of material processed with most of the power consumed by two motors driving the belt.
In the course of this study, several test series were carried out to investigate the triboelectrostatic charging behaviour of various oxides. At the beginning, the influence of the degree of aging and the influence of the sample storage on the charging efficiency of the oxide samples was analysed. For this purpose, two oxide samples were stored under …
