Lignite dryer: 1.Strong regulatability. 2.Sophisticated and stable. 3.Capacity:1-50 t/h. 4.Energy-Saving.
Characteristics of lignite dryer:
(1) Environment-protecting and energy-reducing.
(2) Less investment, small footprint, supporting civil works.(3) Reliable, simple operation, convenient maintenance, safe and durable.(4) Meet the material widely.(5) Ensure the quality of lignite change.(6) Continuous work, large capacity.
Lignite dryer working principle:
The first drying area is in the high humidity status ,removing most of moisture by 400 °C to make sure the chemical composition of the lignite no change and not easy to burn .The temperature of the second area is 300°C, removing the moisture by middle enduring air temperature to ensure the lignite no coking.The temperature of the third area is 120°C-210°C,using the crushing device in the rotary body ,repeating crushing, scattering the material by down-flow drying .The forth drying area is high exhausting area , the temperature is 60°C-80°C,removing moisture by low temperature and hot air that produced by the inducing air system .
The Nanyang product of lignite dryer ,is also used for drying coal slurry, on the condition of ensuring the lignite quality fixed , adopt low-temperature and four grades drying process, to evaporate the moisture of lignite lower than 13%.
Lignite Dryer Applications :
Slime, fly ash, sludge, lignite, desulfurization gypsum, sand, slag, chicken manure, dung, grain distiller's grains,marc, dregs,etc.
