peat rotary drum dryer

Henan Hongsheng Heavy Machinery is the first study to dry coal dryer professional equipment manufacturers, lignite is an important energy and chemical raw materials, but because of high moisture lignite (20% -40%), low calorific value (2700 kcal or so), spontaneous combustion etc. characteristics, resulting in lower selling prices, sales radius is limited, so more and more development and utilization of lignite domestic and foreign governments and research institutions attention.Hongsheng company product of Brown coal 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 evaporatethe mosture of lignite lower than 13%.The first drying area in the high humidity status ,remove most of moisture through 400 °C, to make sure the chemical composition of the lignite no change and no easy to burn;The temperature of the second area is 300°C, to remove the moisture by middle temperature induing air, to ensure lignite no coking,The temperature of the third area is 120°C-210°C, ,use the crushing device in the rotary body,repeatly crushing, scatterthe material,down-flowdrying;The forth drying area is high exhausting area,tmperature is 60°C-80°C,remove moisture by low temperature and hot air which produced through the inducing air system . Applications include: lignite,quality, dry municipal sludge, paper sludge, leather sludge, printing and dyeing sludge, chemical materials and pharmaceutical liquid fermentation residue, food fermentation, sugar residue, rosacea, chemical organic waste and so on.
