Rotary dryers require less energy to dry material, and energy consumption is reduced when running at lower capacities. Fluid bed dryers, however, are considered to be more thermally efficient than rotary dryers, because heat transfer is maximized due to the fluidization effect, which surrounds each granule with the drying air.
The drying machine is a rotary metal drum, which is set at an angle of about 3-5 degrees and rotates at a speed of 2-8R/Min. the coal remains in the drum for 8-12min. The coal drum is uniflow which means the hot fuel gas and coal are fed in at one end and discharged at the other. The heat exchange takes place during the process of gas-solids ...
Process Flow. Feeding: Materials are fed into the rotary dryer's high end. Drying: As the drum rotates, materials are lifted up by flights and dispersed in hot air.
