Lignite is a kind of low-grade coal, which is formed by peat diagenetic formation of humic coal, it’s the lowest degree of coalification, always present brown, dark brown, dim or asphalt luster color, no cohesive. Its physical and chemical properties are between peat and bituminous coal. High water content, high volatile, low density, containing humic acid, oxygen content up to 15 ~ 30%, easy to fragmentation, spontaneous combustion in the air. According to China's coal classification standards, they are divided into two categories: light transmittance PM 30 ~ 50% of the old lignite and PM less than or equal to 30% of the young lignite. Chinese and Indonesian lignite are mostly old lignite.

Dingli New Energy Technology Co., Ltd. engaged in coal, slime drying industry for many years, through the physical and chemical properties of lignite and lignite drying temperature, pressure, wind speed, oxygen content and other related parameters study,we established the lignite drying Machine test base in Inner Mongolia, after the company's technology research and development for a number of experimental demonstration, successfully developed lignite drying upgrading of lignite dryer equipment. 

Our lignite dryer can reduce the moisture content of lignite 25-60% to 15-30%, and the calorific value of treated coal can be increased by 30-40%. It is directly used as a substitute for bituminous coal or anthracite power plant use. The technology and equipment through the practice in Inner Mongolia, Yunnan, Xinjiang and Indonesia, safe and stable, energy saving and environmental protection, with great market potential for a variety of lignite mining enterprises
