DDHG lignite the Mongolian coal drying technology core, lignite Mongolian coal dryer price Advisory 
 The DDHG lignite the Mongolian coal dryer drying principle: raw coal crushing by belt conveyors to feed box, then slide into the guide plate by a big dip in the tumble dryer to quickly oriented tilt lifting and with drum rotation and the inclination of the cylinder, since raised to the top of the barrel cylinder bottom fall, the formation of a "material curtain" high temperature flue gas into the drying drum with the same end of the wet material through which the wet material to form a conduction and liquid heat In exchange, preheat the wet material and evaporation of the water. Meanwhile, the high-temperature flue gas temperature is decreased rapidly, by preheating the wet material into the medium-temperature drying stage at this stage, most of the moisture is evaporated. With repeated mixing of the materials and flue gas exchange, until it reaches the thermal equilibrium moisture requirements of the material is reached, the material is discharged drying drum, complete lignite drying. 
 Dongding DDHG lignite Mongolian coal dryer device in Shanxi, Inner Mongolia, Hebei, Jiangsu, Liaoning, and put into use, and achieved good effect. Zhengzhou Dongding dry, the industry's most professional the lignite dryer manufacturers, please look DDHG brand!
