Electrostatic Beneficiation of Coal Using a Cyclone-Tribocharger

摘要: A preliminary study is presented on a new method of separation mineral inclusion from coal. The process involves triboelectrical charging pulverized coal by cyclone-tribocharger and electrostatic differential deflection the tests for Australian with 18.5 percent ash content using this separator yielded following results: cyclone copper wall gives best performance; percentage contents particles collected anode cathode are 26 11 percent, respectively; coarse 74-150 pm diameters showed beneficiation rate better than that fine below 44 pim. In order to understand these results, authors experimentally examined behavior pure fed either or teflon walls fluidization-charger. Avoidance particle-to- particle collision choice material important in raising performance. On basis microscopic observation, confirmed liberation most crashed less 70-?m diameters.
