The air dense medium fluidized bed dry coal separator uses gas-solid phases as the dense medium for coal separation, where the solid phase is magnetite powder. When fluidized, the state of the gas-solid phases of the bed performs like a fluid, and the heavy and light materials are separated by their densities. There are several factors ...
The beneficiation of different size fractions (+5, −31 mm) of coal using an air-fluidized bed dry dense-medium separator with silica/zircon sands as the fluidizing-bed medium has been studied. Particle size and bed height were found to strongly influence the efficiency of separation with the dry dense-medium separator. An increase in bubble size associated with increase in bed height to 15 ...

include models for screening, medium make-up and dense medium separation through cyclones. As far as the authors are aware, a dynamic model for a dense medium drum (DMD) separator is not available in the open literature. Since a drum separator is an integral unit process required in coal beneficiation (King, 1999) it is necessary that a dynamic
Dry coal beneficiation with an air dense-medium fluidized bed is one of the dry coal processing methods that have proved to be an efficient separation method with separation efficiencies comparable those of the wet heavy medium separation process. Although the applications of the fluidized bed dry coal separator have been done successfully

The chronology of the development of dynamic dense medium separators is depicted in Figure 1. Figure 1 - Dynamic Dense Medium Separator Development DMS LABORATORY TESTING To determine if an ore is suitable for pre-concentration using DMS (or other gravity separation techniques), a laboratory scale testing program is generally initiated.
Dense medium separation (or heavy medium separation (HMS), or the sink-and-float process) is applied to the pre-concentration of minerals, i.e. the rejection of gangue prior to grinding for final liberation. It is also used in coal preparation to produce a commercially graded end-product, clean coal ...

Fluidizing the raw coal itself using air is an efficient way to dry beneficiate coal for finer size fractions [29, 30]. Separations by density are effective in the dry dense-medium separator because objects that are denser than the density of an air-fluidized bed of sand particles will sink and those less dense .
