Low Density Dry Coal Beneficiation Using an Air Dense

Sep 01, 2007 Dry beneficiation with an air dense medium fluidized bed is an efficient method for separating coarse coal of 6-50 mm, which uses gas-solids phases as the separation medium[1>3]. This method differs from conventional air jig or shaking table separation methods, which use air as the separation medium and have low separation efficiencies.

DRY BENEFICIATION AND CLEANING OF CHINESE HIGH-ASH COARSE

Dry dense-medium fluidized bed separation provides a new alternative approach for coal beneficiation and cleaning. An indicator of segregation degree Sash was proposed to evaluate the stratified performance of coal samples by bed density. Fluidization stability of the bed was greatly enhanced by mixing a certain amount (21.53%) of fine magnetite powder (< 0.15 mm) into the fluidized media

Studies on Bed Density in a Gas-Vibro Fluidized Bed for

Dry coal beneficiation has played a vital role during the initial stage of coal cleaning in recent years. Successful utilization of a gas–solid fluidized bed for >6 mm coal cleaning motivates scholars to explore the possibility of fine coal cleaning using dry beneficiation methods. In this study, pulsed flow was introduced into a fluidized bed to optimize bubble behavior, thus improving the
