Professional production in Inner Mongolia, Yunnan, Indonesia, Heilongjiang, Fujian the lignite dryer, highest quality lignite dryer system Dongding for you to create, Division I of the lignite dryer formation normalized serialization provided 300 tons of lignite drying dry machines, 500 tons of lignite drying machine, 600 tons of lignite drying machine, 700 tons of lignite dryer, 1,000 tons of lignite dryer, 1,500 tons of lignite drying machine products, 2,000 tons of lignite dryer. Efficient lignite drying equipment Drying Equipment Co., Ltd., Zhengzhou City Dongding new lignite drying system developed these characteristics. The dryer design take full account of the nature of the dry material, specially designed for the high water content of lignite in the internal structure of the cylinder on, and further strengthen the unity block materials anti broken, not only to improve the thermal efficiency and effective avoid the coal phenomenon too dry in the dryer. The system through the processing of lignite drying and dehydration, which can effectively improve the the lignite heat indicators and reservoir shipment performance, so that the indicators meet the requirements of commodity thermal coal, has obvious economic, environmental and social benefits. 

 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.
