We provide the industry's most professional technological transformation of lignite dryer after-sales service one-stop service Dongding lignite drying machine drying professional equipment maker, Division I the lignite dryer technology industry's leading lignite-producing areas in the country, has been vigorously promote the use of lignite dryer Division I process design, install production, the lignite dryer transformation integration services. Lignite in the context of the increasingly tense domestic coal resources is a new way to the development and utilization, the East Ding dried accumulated a wealth of experience and theory and practice for many years engaged in slime, clean coal and other coal dehydration and drying. Engineering and technical personnel of the Division I for the characteristics and use of lignite point to address a range of safety, environmental issues, the successful development of a dedicated lignite dryer device, the system is a vertical drying in the country after the Division I both developed slime dryer device the field is a major breakthrough, greatly expanding the use of lignite ways. Currently the lignite dryer system in Division I in Inner Mongolia, Liaoning, Yunnan has been quick to promote the use to solve the practical problems of the customer, won customers welcome owners friends come to visit our company exchange. Division I to the lignite dryer system installed for customers in Dandong, the system configuration Division I newly developed the lignite drying dedicated large burner stove, completely solve the problem of lignite drying heat source selection troubled. 
 The Dongding lignite dryer technical characteristics 
 (1) dry lignite does not damp absorbent: After drying lignite larger physical and chemical changes, i.e., the pores collapsed, the crosslinking reaction and tar migration pores forming a seal, the result montanic becomes more and more hydrophobic, and also be able to montanic hardening was observed, which also led to the formation of the rigid structure of the lignite. As a result, lignite from soft coal is converted to hard coal, is hydrophobic and hydrophilic conversion to stamp out lignite dry damp absorbent, which can achieve the long-distance transport of lignite. 
 (2) dry lignite volatiles can be effectively protected: the humidity content of the carrier wet medium, without volatile release conditions; 
 (3) a high degree of automation, simple manipulation: a high degree of system integration, and with automatic intelligent monitoring system, the hot stove furnace, the inlet of the dryer, the dryer outlet and induced draft fan entrance of the main parts of the temperature, pressure, flame, smoke real-time monitoring of oxygen and other parameters, to achieve automatic control and regulation system running, the parameter continuous automatic acquisition, fault alarm and safety interlock protection. Vibrating feeder, dryer, cited devices such as fans, blowers, spiral feeder with frequency control, according to the needs of production and operating parameters, using the appropriate speed, not only can easily control the final moisture indicators but also save a lot of power. 
 (4) Energy efficient: dry heat loss (drying) machine, high thermal efficiency; heat source coal burnout rate of pulverized coal up to 99% of the hot stove, the effect of heat transfer efficiency than traditional coal-fired hot air furnace section Coal 30 --- 50%; lignite powder produced by the drying process can be used as a fuel, which greatly reduces the cost of fuel. 
 (5) Safety: seamless wind phenomenon unique sealing structure to discharge completely solve the sealing difficulty to achieve full oxidation negative pressure operation to eliminate the possibility of lignite combustion and explosion, safe and reliable operation.
