Large output Rotary Drum Dryer for Slag, coal, wood, bagasse

Rotary dryer  is widely used in mining industry, building material, metallurgy, chemical industry, cement industry, and etc.

Our factory is a professional manufacture of rotary drum dryers. we've designed various rotary dryers for drying slag, limestone, coal powder, clay, sawdust, oil palm fiber, grass, river stone, poultry dung, ores, rock sand and etc for our customers both at home & abroad. 

1. The description of sludge rotary drum  dryer

Sludge rotary drum dryer is also called roll dryer, which is handling by bringing it into direct contact with a heated gas. The dryer is made up of a large, rotating cylindrical tube, The dryer slopes slightly so that the discharge end is lower than the material feed end in order to convey the material through the dryer under.

2. The most outstanding advantage of the sludge rotary drum dryer

1) high dry capacity,

2) smooth rotation,

3) high output. 

4) perfect combiantion of drying and cooling.

3. Other features:

This kind of Sludge rotary drum dryer 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. 

4. 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.
