Qualified rotary sludge drier of Nanyang

Sludge rotary drier of Nanyang: 1.the temperature of out air is low 2.the fuel can be coal,gas and oil 3.widely applications

The description of sludge rotary drier:

Sludge rotary drier is also called roll drier, which is handling by bringing it into direct contact with a heated gas. The drier is made up of a large, rotating cylindrical tube, The drier slopes slightly so that the discharge end is lower than the material feed end in order to convey the material through the dryer under.This kind of Sludge rotary drier has introduced advanced technology,through continuous transformation, it has been able to meet production needs of different countries. Recently years, we've recieved a lot of praises from many cuontries which means it is popular worldwide. 

 

Features:

1.Adopting the heat change technology from Krupp company, this machine has the advantage of

high efficiency and less energy consumption.

2.The efficiency of self heat preservation is higher than 80%, for single cylinder type, it is 35%

3.Compared with the single cylinder type with same capacity, the 3cylinder type only cover the 

50% ground. It will save the 50% of building cost, 60% power cost, and above 60% fuel.

4.The fuel can be coal, oil and gas.

5.With the heat resisting, hear wearing alloy steel plates, its life is 4 times as the common steel 

plates.

6.The water content of the product is less than 0.5%

7.The temperature of out air is low, and it will increase the life of the dust catching system.

8.Without the big and small gears, it work with riding wheel.

9.Simple operation, it is easy to adjust the date of the water content of the product.

 

Working principle:

Material to be dried enters the dryer, and as the dryer rotates, the material is lifted up by a series of internal fins lining the inner wall of the dryer. When the material gets high enough to roll back off the fins, it falls back down to the bottom of the dryer, passing through the hot gas stream as it falls. This gas stream can either be moving toward the discharge end from the feed end (known as co-current flow), or toward the feed end from the discharge end (known as counter-current flow). The gas stream can be made up of a mixture of air and combustion gases from a burner, in which case the dryer is called a direct heated dryer. Alternatively, the gas stream may consist of air or another (sometimes inert) gas that is preheated. When the gas stream is preheated by some means where burner combustion gases do not enter the dryer, the dryer known as an indirect-heated type.
