Lignite drying and quality lignite drying and quality technology Dongding Drying: lignite is an important energy and chemical raw materials, but because the characteristics of the lignite, resulting in low sales prices, sales radius restricted, so the development and utilization of lignite more by the great importance of the domestic and foreign government, research institutions and drying equipment manufacturers. The Zhengzhou Dongding breakthrough lignite drying quality and technical barriers, the project is put into use in the main producing areas in the lignite. 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 special lignite drying plant, the system is Division I following the development of slime dryer unit in the vertical dry areas a major breakthrough, 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 of the lignite drying dedicated large-scale burner stove, completely solve the problem of lignite drying heat source selection troubled. 
 Lignite dryer design of Dongding take full account of the nature of the dry feed lignite high water content in the cylinder on the internal structure specially designed to further strengthen the anti-fragmentation of the unity block material not only improves the thermal efficiency , and effectively prevent the excessive dryness of the coal in the dryer. The lignite drying dehydration, which can effectively improve the heat index lignite and Chu shipment performance, so that the indicators meet the requirements of commodities steam coal has obvious economic, environmental and social benefits. 
 Lignite drying machine according to the different material properties (moisture, ash, particle size) to change the operating parameters, so that material can form a stable cut fabric curtain in the dryer cylinder body, the quality of heat exchange more fully; 
 2, dryer strong anti-overload; 
 Dryer coated with high temperature paint to prevent heat finish off the dryer during operation; 
 Dryer to achieve a "zero thrust, greatly reducing wear riding wheel block, cylinder smooth and reliable; 
 5, lignite dryer aligning supporting roller device, riding wheel and rolling circle with linear contact forever, and thus greatly reduce the wear and power loss; 
 Dryer no power auger feed, not only to solve the problem of sealing and bonding, while the intermittent feed into a continuous feed. Lignite drying and quality, drying and quality technology selected Dong Ding, and quality assurance.
