In a triboelectrostatic separator, particles are charged by the triboelectric effect before electrostatic separation. The purpose of this work is to develop a new system to provide the required electric potential to the electrodes of a separator by triboelectric charging, and to use the resulting charge for mineral separation.
The triboelectric belt separator technology has been used to separate a wide range of materials including mixtures of glassy aluminosilicates/carbon (fly ash), calcite/quartz, talc/magnesite, and barite/quartz. Overall, the separator design is relatively simple with the belt and associated rollers as the only moving parts.
Li used a tribo-aero-electrostatic separator to model the trajectories of plastic granules numerically and found that such trajectories depend on the size, charge/mass ratio, and initial position of the granules as well as the geometrical dimensions and operating conditions of the separator (Li et al., 2013).

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.
The triboelectric separator was built to conduct triboelectric separation experiments. As shown in Fig. 7, the separator consists of air supply system, screw feeder, tribocharger, separation chamber, collecting chambers and power supplies. Particles are fed by the screw feeder controlled by a speed controller.
The triboelectric separator with this feeding method can realize the self-flow of mineral particles without increasing other energy consumption [27]. However, for this …

The triboelectric belt separator technology has been used to separate a wide range of materials including mixtures of glassy aluminosilicates/carbon, calcite/quartz, talc/magnesite, and barite/quartz.
The rotary triboelectric separator has been widely recognized for its high charging performance and separation efficiency [17,[23], [24], [25], [26]]. In our previous study, ash removal and quality enhancement of low-rank coal is accomplished by effectively removing hazardous trace elements (i.e., Cd, Cr, Pb, and Sb) utilizing a rotary ...
A batch-mode triboelectric separator is being used in CSIR-Institute of Minerals & Materials Technology for separating pure coal particles from gangue quartz and kaolinite particles.

The operation of the tribo-electrostatic separators is mainly based on the triboelectric charging of particles with opposite polarities using a tribo-charging device. First, the granules get an electric charge and then are fed into the separator; the particle trajectories are then deflected according to the polarities of the electrodes and the ...
A descriptive schematic of a triboelectric separator is represented in Figure 1. First, the particles enter a rotating cylinder, where they undergo several 'particle-to-particle' and 'particle-to-wall' collisions. These collisions allow the granules to be charged, and thus they exit from the rotating cylinder by falling vertically into ...
