Abstract
Numerous research studies have been made on the electrostatic separation of granular insulating materials, with many industrial applications in the area of waste electric and electronic equipment (WEEE) recycling. However, very few investigators have studied the separation of finely-ground matter (i.e., granule diameter < 1 mm), in relation with applications in mineral processing, or in food industry. The aim of this work is to evaluate the effect of particle size on the selective sorting of fine particles in a two-rotating-disks-type tribo-aero-electrostatic separator. The experiments are carried out on a synthetic mixture composed of 50% Acrylonitrile Butadiene Styrene (ABS) and 50% Polystyrene (PS) particles of size 250 to 2000 microns. The performance of this separator is evaluated by setting up a measurement system that enables the continuous and simultaneous recording of the charges and the masses of the separated products. The conclusions of this study will serve at the optimum design of an industrial electrostatic separator for the recycling of micronized plastics from WEEE.
