Raw lignite dryer can dry and wet slurry dewatering, drying can be guaranteed to be slime, lignite quality without changing the slime dehydrated to a moisture content below 13%, improve combustion efficiency and make fuller use of coal resources. Use of valuable resources slime, so that turning waste into treasure, not only can generate considerable economic benefits, but also to solve the slime occupation of land and pollute the environment stacking a series of problems. Lignite, also known as wood coal, is the lowest mineral coal rank coals. A cross between peat and bituminous coal between the brown-black, dull lower rank coals. Because it is rich in volatiles, so easy to burn and smoke. The cross section can be clearly seen traces of the original wood. Containing alkali-soluble humic inside. Carbon content of 60% to 77%, a density of about 1.1-1.2, more than 40% volatile components. No glial layer thickness. Calorific value of approximately 23.0-27.2 MJ / kg (5500-6500 kcal / kg). Mostly brown or brown-black, the relative density of 1.2 to 1.45. Lignite dryer dried lignite from hydrophilic to hydrophobic conversion, the result is: lignite to hard coal from soft coal conversion, which can achieve long-distance transport of lignite. In the development and utilization of lignite, Kuwait demand for lignite, to create a high-quality lignite dryer, the current technology is widely used lignite, small investment, the effect is obvious. With economic development and gradually increase the demand for energy, in reality, on the development and utilization of lignite has become very common, as the market demand continues to increase in lignite, brown coal processing and development of technology has also been in practice constantly upgrading, including lignite drying technology is currently more advanced process technology, improving quality lignite is dry, add some organic binder been to effectively deal can form a briquette product, suitable for large-scale promotion use, and in the process lignite dryer play an irreplaceable important role. At present, Zhengzhou Dongding Drying Equipment Co., Ltd. has formed a specialization, scale, serialized products structural system that can handle high water, fine grain size, viscosity of the Wei coal, flotation tailings, coal, coal, coal tailings filter press , the last coal, coal or ore powder material and the water is high, burning low, high volatile lignite low, Mongolian coal and other materials. Techniques for different materials for process design and equipment selection to ensure drying effect. Drying Equipment diameters from Φ1.6 ~ Φ4.5 m, length 15 m - 40 m from a variety of daily processing capacity from 200 to 3000 tons, feed moisture 40 ± 5%, drying moisture can be reduced to 10 ± 2% or even less than 80% thermal efficiency, system security, environmental protection, energy efficient, automated control. Division I mention the quality of the coal drying system in Inner Mongolia, Shanxi, Henan, Hebei, Heilongjiang, Liaoning, Guizhou, Yunnan and other regions get widely used. "Customer satisfaction" is our highest pursuit and ultimate goal; class technology, excellent quality, excellent service, competitive price, welcome friends come to visit, to discuss cooperation and seek common development.
