Lignite dryer,Dryer manufacture

Lignite dryer, or brown coal dryer. Lignite is an important energy and chemical raw material, but because of high moisture content(20% -40%), low calorific value (2700 kcal or so), spontaneous combustion characteristics, it has very low selling prices, limited sales radius, so more and more development and utilization of lignite drying is under taken in domestic and foreign governments and research institutions.

Previous drying method generally use centrifugal dewatering, the equipment are expensive, but low capacity, small dehydration rate, usually only once reducing 10% moisture with 15 - 20% water content remained. Rotary dryer lignite, brown coal is taken to break distributed first and then the dry heat of new technology enters, so that drying of materials in a row, industrialization and automation. Treated by the wet lignite lignite drying process the water can be reduced from 25%-45% to 13%. It has very good economic, social and environmental benefits.

(1), environmental protection and energy and reducing loss of lignite. Improve the calorific value of brown coal, desulfurization, reduce volatile.
(2), investment, small footprint, supporting civil works less.
(3), reliable, simple operation, convenient maintenance, safe and durable.
(4), dry and moisture control, the minimum up to 5% or less, meet the material widely.
(5), even temperature drying process to ensure the quality of lignite change.
(6), continuous work, large capacity.
