| Abstract: | The distribution of moisture on coal surface and the influences of transfer behaviour of moisture in the airsolid fluidized bed on coal separation are analyzed. Some moisture parameters under different technological conditions are put forward. And a new technique suitable for fast drying of coal with coarse particles is introduced. The technique may solve the problem of moisture on coal surface with a fast drying velocity and a high efficiency, but a low cost. |
