Lignite is a kind of coal and its degree of coal-gasification is only higher than that of coal slime, it is a kind of low - grade coal between peat and bituminous coal. Lignite is rich in volatile ingredients, so it burns easily and smokes easily. Meanwhile, lignite has two high and three low characteristics: high water content (generally 32-42%), high volatile content (generally 40-50%), low calorific value (generally below 3000 kcal), low density and low ash melting point.

  For the above reasons, lignite is difficult to be widely used as industrial thermal coal, so the economic value of lignite is not reflected. Under the current global energy shortage, the economic value of lignite is valued by the world energy community. The development and application of lignite drying and upgrading technology is the basis and condition for large-scale industrial application of lignite.
  The energy-saving lignite dryer developed by Zhengzhou Dingli uses scientific technology and advanced equipment to dry and remove lignite, comprehensively improve the economic value of lignite, and promote the energy-saving development and wide application of lignite resources. Its main components are: pulverizer, conveyor, feeder, heat source, rotary dryer, discharge device, air intake system, dust removal equipment, temperature control device, electrical system and so on.
