Quality lignite dryer select Dongding dry really meet your needs, we provide you with a medium-sized series of lignite dryer (700 tons of lignite dryer, 800 tons of lignite drying machine, 1000 tons of lignite drying machine), I brown coal drying technology in the industry-leading, lignite producing areas in the country has been vigorously promoting the use of the current Division I lignite dryer process design, installation produced lignite dryer transformation of integrated services. Lignite in the context of the increasingly tense domestic coal resources currently a new development and utilization of channels, Dongding dry for many years engaged in the slime, clean coal and other coal drying dehydration accumulated a wealth of experience and theory and practice. Engineering and technical personnel of the Division I for the characteristics of lignite and point to solve a series of safety, environmental issues, the successful development of a dedicated lignite dryer device, the system is in the country in Division I is the development of slime dryer device vertical dry another major breakthrough in the field, greatly expand the use of lignite way. Division I of the lignite dryer system in the region of Inner Mongolia, Liaoning, Yunnan has quickly promote the use of to solve the practical problems of the customers won praise customers, owners are welcome friends come to visit our company exchange. Lignite dryer system installed by the Division I in Dandong, the system configuration of our latest development for the lignite drying large burner stove, completely solve the problem of lignite drying heat source selection troubled. 
 Technical characteristics of the Dong Ding lignite dryer 
 (1) dry lignite does not get damp absorbent: dried lignite to a greater physical and chemical changes, ie, the pores collapse, the crosslinking reaction and tar migration to seal the pores formed, the results of lignite has become more and more hydrophobic, but also to The observed hardening of lignite, which also led to the formation of the rigid structure of the lignite. The result is a brown coal from the soft coal is converted to hard coal, by the hydrophilic conversion of hydrophobic to eliminate the damp absorbent lignite dry, which can achieve the long-distance transport of lignite. 
 (2) dry lignite volatile after the effective protection of: humidity content contained wet media, there is no volatile release conditions; 
 (3) high degree of automation, simple manipulation: a high degree of system integration, and is equipped with automatic intelligent monitoring system on the hot stove furnace, the entrance of the dryer, the dryer outlet and the entrance of the main parts of the induced draft fan, temperature, pressure, flame, smoke real-time monitoring of oxygen and other parameters, the system operation to achieve automatic control and regulation parameters for automatic acquisition, fault alarm and safety interlock protection. Vibrating feeder, dryer, cited in devices such as fans, blowers, screw feeder frequency control, according to the need of production and operation parameters, with the proper speed, not only can easily control the desired final moisture index and save a lot of power. 
 (4) Energy efficient: dry (drying) the loss of hot, high thermal efficiency; heat source using pulverized coal burn rate as high as 99% of the pulverized coal hot stove effect of heat transfer efficiency than conventional coal-fired hot-blast stove section coal 30 --- 50%; lignite powder drying process can be used as fuel, greatly reducing the cost of fuel. 
 (5) Safety: a thorough solution to the sealing difficulty to the nesting unique sealing structure seamless wind phenomenon, full free oxidation of negative pressure operation, put an end to the lignite combustion
