Characteristics of lignite rotary 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 rotary 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 rotary 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 rotary Dryer Applications :

Slime, fly ash, sludge, lignite, desulfurization gypsum, sand, slag, Chicken manure,  dung, grain stillage,marc, dregs,etc.

 

Lignite rotary dryer market outlook:

With the implementation of the strategy of sustainable development, the rational development and utilization of coal and other mineral resources has become an important issue. The full development and utilization of lignite is urgent. Use the valuable lignite resources, not only can bring us considerable economic benefits, but also can turn the waste into wealth. Nanyang lignite dryer can ensure the quality of brown coal, reduce the sulfur content of lignite to improve the calorific value of it. And can also improve combustion efficiency, making more full use of coal resources.
