tribocharging and electrostatic separation of plastics and reported that tribocharging is a statistical process [14] Based on the collision between particles Chahinez introduced a simple mathematical model for simulating the outcome of tribo aero electrostatic separation process involving mixture of three granular materials [15]
ABSTRACT The contact electrification also designated as the triboelectric effect is commonly used in association with the electric field forces for the electrostatic separation of positively and negatively tribocharged granular plastic mixtures that have otherwise similar size density magnetic properties and electric conductivities However the wide scale industrial
Most separation techniques for waste electrical and electronic equipment WEEE require preliminary scrap granulating operations to carry out mechanical component dissociation Electrostatic separation is the selective sorting of electrically charged or electrically polarized granular WEEE under the action of the electric field forces
