New type energy-saving rotary dryer uses new type combined lifting device. The structure of the dryer is novice and unique. It is adaptive to various kinds of coals, because of the high temperature fluidization bed, being able to use poor quality coal, gangue and coal dregs. It optimize three technical parameters of drying system: “coal, material, and air? greatly increasing the efficiency of the dryer, increasing output and reducing the energy consumption.
