Lignite Dryer - China

price: contact company for price

Lignite is the mineral coal with the lowest degree of coalification. It

is a low grade coal with brownish black like the color between peat and

pitch coal, and unpolished. As it is rich in vdaf, it is easy to burn

and smoke. The woody trace can be seen clearly from the section. The

lignite contains humic acid that is soluble in alkali liquor. Its carbon

content is 60%~77% and its density is about 1.1~1.2 and volatilization

component is more than 40%. Without thickness of colloidal matter layer,

its heat value is about 23.0-27.2 MJ/kg (5500-6500 kilocalorie/kg). its

color is brown or brown black with 1.2~1.45 relative density.

The previous drying adopts the centrifugal mechanical dehydration method whose equipment is expensive, output is low, and dehydration amplitude is small with 10% dehydration rate once and 15-20% moisture remains. The rotary lignite dryer adopts new technology of breaking and disperse the lignite before drying it by heat which realizes the serialization, industrialization, and automation of drying process. After the lignite drying fabrication processing, the moisture of the wet lignite decreases from 25%-30% to less than 13%. It can be used as fuel coal and has favorable economic, social and environmental benefit after perfecting the coal washing and screening techniques.
