POC-SCALE TESTING OF A DRY TRIBOELECTROSTATIC SEPARATOR

The bench-scale test program is aimed at studying the charging mechanisms associated with coal and mineral matter and improving the triboelectrification process, while the POC test program is aimed at obtaining scale-up information. The POC tests will be conducted at a throughput of 200-250 kg/hr. It is also the objective of the project to conduct a cost analysis based on the scale-up

TECHNICAL PROGRESS 'REPORT

Bench-Scale Triboelectrostatic Separator Many electrostatic separators are based on passing charged particles through an electric field so that positively charged particles are collected on the negative electrode (cathode), while negatively charged particles are collected on the positive electrode (anode).

TECHNLCAL PROGRESS REPORT

Tasks associated with the fabrication and set-up of the bench-scale triboelectrostatic separator were continued during the past quarter (see Figure 4). During the construction of the separator, problems were encountered in finding the proper materials for fabricating the electrodes and electrode supports. In determining the material for the electrodes, a number of factors were considered

POC-scale testing of a dry triboelectrostatic separator

Prior to the POC testing, bench-scale test work will be conducted with the objective of increasing the separation efficiency and throughput, for which changes in the basic designs for the charger and the separator may be necessary. The bench- and POC- scale test work will be carried out to evaluate various operating parameters and establish a reliable scale-up procedure. The scale-up data will

Separation of unburned carbon from coal fly ash: A review

15/07/2019· A bench-scale parallel triboelectrostatic separator has been used for beneficiation of weathered fly ash particles by Cangialosi et al. . Two different configurations of the electrodes were adopted to determine the mass fractions of positively and negatively charged particles, i.e., charge distribution, in raw fly ash. It was found that weathered ash particles had an average zero charge
