2.used well for slurry and paste materi
Principle of sludge paddle dryer
LDG Oar blade dryer is a kind of conduction heating and low rotating speed-stirring type drier. There is jacket on the body of drier, hollow oar blade on the hollow shaft, filling heating medium in them, wet material is stirred by oar blade and carries on heat exchange with shaft and oar blade. The structure of machine is generally horizontal type with two or four shafts.
Features of sludge paddle dryer
1 The thermal efficiency reaches as high as 80%-90%. Heat transfer coefficient K is 100-300Kcai/h.m2°C. Evaporation capacity is 10-30Kcai/h.m2.
2 Operation method: support continuous operation and batch operation, support vacuum drying for thermal sensitive material and normal drying. Support heating, evaporating and cooling.
3 Heating resource: heat conducting oil, steam, water, hot air and cooling fluid.
4 Special structure of oar blade with large heating area. The unit volume is small.
5 Heating area is large in unit volume.
6 It is widely used for organic and inorganic substance, granule material, sticky material and the material with high water content.
