Coal is one of the most important primary energy resources worldwide. Because of the shortage of water resources, dry coal beneficiation has become a research hotspot. A pulsating air dense medium fluidized bed (PADMFB) that introduces a pulsating air flow to the air dense medium fluidized bed was proposed for fine coal particles. In order to investigate whether coal particles can be separated by...
Coal is one of the most important primary energy. Coal firing is the principal cause of global warming and acid rain. With the worsening environmental pollution, the coal preparation becomes very important. In this study, a novel technology based on active pulsing air dense medium fluidized bed (PFB) for fine coal preparation was investigated. The forces acting on particles under different conditions...
