Lignite coal in brownish black, without any gloss, is one of coal resources with the lowest coalification degree. The lignite coal with great tendency to be weathered in open air, is strong in chemical reactivity, difficult in storage and transportation and severe in air pollution. Since the high-quality coal is almost used out, the lignite coal has become the commonly-used alternative. With high water content inside, the lignite coal is about 40% high in volatile degree. Rich in free humic acid, the lignite coal is easy to be weathered and cracked in open air.

Featuring in low ignition temperature about 270 ℃, the lignite coal is easy to be self ignited as long as being stored for more than two months. Since the height for piling up should be no more than 2m, the lignite coal is not suitable for long-distance transport. Lignite dryer machine, with hot air as drying medium, works by formulating heat and mass exchanges between lignite coal and hot air. Lignite coal, with high water content inside, exchanges heat with hot air under negative pressure by the way of convective heating.

The finished lignite, being agitated, dispersed and cracked in the lignite dryer, slowly moves forward and finally discharged out the rotary drum. Morality oriented, people will be honest; quality rooted, product will be excellent.
