: Dry Electrostatic Separation of Fine Coal Semantic

A current research project in the PETC Coal Preparation Division focuses the beneficiation of fine dry coal powders after triboelectric charging. In this process, the fine coal powder is entrained in a gas stream and made to impact on a metal surface under turbulent flow conditions. This forceful turbulent contact causes differential charging of the organic and inorganic phases in the coal.

2015-3-1 The effect of feed rate varied from 0.9 kg/h to 13.6 kg/h on the electrostatic separation performance is shown in Fig. 2.It indicates that the feed rate increases from 0.9 kg/h to 9.1 kg/h results in the continuously decrease of clean coal ash content from 49.64% to 31.16%.It is because higher feed rate introduces more particles participating in the tribocharging process in the charging ...
