Coal drying Dongding, dry and has accumulated a wealth of experience and theory and practice in many years engaged in the slime, clean coal and other coal dewatering drying. Engineering and technical personnel of the Division I for the characteristics of the lignite and the use of point to solve a series of security, environmental issues, and successfully developed a dedicated lignite dryer device, the system is Division I only develop slime dryer unit in the vertical dry areas a major breakthrough, greatly expand the use of lignite way. Division I of the lignite dryer in the region of Inner Mongolia, Liaoning and Yunnan has quickly promote the use of to solve the practical problems of the customers won praise customers, welcome to the majority of the owners friends come to me for inspection and exchange. Lignite dryer system installed by the Division I in Dandong, the system configuration of our latest development of the lignite drying dedicated large burner stove, completely solve the problem of lignite drying heat source selection troubled. 
 Lignite dryer process principles: be dry lignite is crushed by belt conveyors to feed bins, and then slide the drum dryers by the inclination of the guide plate to be quickly directed to tilt lifting area, and with the rotation of the drum and cylinder 
 Tilt, is mentioned since the barrel end of the tube top down to form a material screen, high-temperature flue gas from the same side with the wet material into the drying drum through the wet material to form a conductive liquid heat exchange to preheat the wet material and evaporation of the water. The same time, the high temperature flue gas temperature rapid decline in temperature drying stage after preheating the wet material, most of the water was evaporated at this stage. With the materials and the repeated mixing of the flue gas exchange until they reach thermal equilibrium to reach the water requirements of materials, the material is discharged drying drum. Inside the drum copy board strip pore structure of lignite so he took the process inside the drum, and continue to leak, both to increase the contact area of ??the lignite and the hot flue gas, to avoid, so he took a rupture caused by too high a one-time whereabouts. significantly reduce the lignite recrushing volume. Copy board between the level of scattered layout has a certain angle with the cylinder axis, both so he took a continuous lignite formation material curtain, but also make the dry material continuously forward to the discharge end, the formation of continuous drying. Are made of thin stainless steel plates to seal between the drum front head and the back-end head and the drum, the lateral plates of stainless steel tension springs and rollers outside of the ring closed, this sealing method can be high temperature, no noise, no leakage gas, is a new type of seal. After a heat exchange contains a lot of water vapor and dust exhaust after the cyclone, to get rid of most of the dust into the bag filter purification, the purified exhaust the direct discharge to form the entire drying process.
