Electrostatic technologies have emerged as the solution of choice for the recycling of insulation contained in the waste materials. The main objective of this work is to contribute to the better understanding of the operating conditions of a new class of tribo-aero-electrostatic separators. The study of the motion of charged particles under the influence of an electric field by the numerical tools facilitates the construction, implementation and control of new electrostatic separation equipment. In effect, the trajectory of the particle can be determined precisely by the equation of forces that act on it in the electric field of the separator. COMSOL software was employed for the analysis of the electric field. A program written in MATLAB served then to simulating the trajectories of electrically charged insulating particles in the separator and enables the study of the factors that might influence the process of selective sorting of the various granular materials.

Among the separation techniques used in industry, the triboelectric separation of insulating particles using rotary tube is an efficient technology employed in waste recovery and mineral industries. This process, also called free-fall triboelectric separation, is widely used for the sorting and the purification of granular materials resulting from industrial plastic wastes. This paper aims at the achievement of a comprehensive description of a laboratory triboelectric separator built up by the authors and its utilization for an experimental study carried out on granular samples containing particles of polyvinyl chloride (PVC) and polyethylene (PE). Thus, among the variable factors of the process, we analyzed the influence of the most important ones, i.e., the rotational speed of the cylinder n (rpm), the applied high voltage U (kV), the charging time of the particles t (s), the mass of the sample m (g), and the composition percentage of the sample C p (%).
