Keywords: Fly ash, rotary triboelectrostatic separator, plate voltage, numerical simulation 1. Introduction Fly ash is the main solid waste of coal-fired power plants and heating boilers. In 2015, China's fly ash yield reached 570 million Mg, which causes serious threat to eco-environment and human health.
This study was performed to investigate the feasibility of applying a Rotary Triboelectrostatic Separator (RTS) to the beneficiation of Eshidiya phosphate minerals. RTS separation tests were ...
The aim of this study is to remove PVC from mixed plastics (PVC/PET) using fluidized bed tribo charger (pipe line). Hence, we designed a bench scale triboelectrostatic separator unit and thus investigated the charge polarity and charge density of PET, PVC on charging materials and various factors such as charging materials, air velocity (the …
The configuration of the rotary triboelectrostatic separator is shown in Fig. 1. Since coal and silica particles are subjected to different electric forces, they got separated in the separation chamber. Three collection bins were used to collect the separated products with different surface charge density below the separation chamber.
As the main solid wastes of coal-fired power plants, fly ash particles with different electrical properties are usually recycled using triboelectrostatic separator. The purpose of this study was to investigate the effect of different plate voltages on the separation of fly ash in a rotary triboelectrostatic separator with experiments and …
