High Efficiency Industrial Sawdust Rotary Dryer For Sales! 

 

The Sawdust Rotary Dryer is a type of Sawdust Dryers employed to reduce or minimize the liquid moisture content of the material it is handling by bringing it into direct contact with a heated gas.

The Sawdust Rotary Dryer is made up of a large, rotating cylindrical tube, usually supported by concrete columns or steel beams. 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 gravity. 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. Often, indirect heated dryers are used when product contamination is a concern. In some cases, a combination of direct-indirect heated rotary dryers are also available to improve the overall efficiency.

Brief Introduction Of The  Sawdust Rotary Dryer 

  YUHONG has much experience in drying wood chips and sawdust. Throughout the year our dryers use residual heat (for instance from electricity generation) for drying wood chips and sawdust. The drying of wood increases the combustion value and lowers storage costs (less sensitive to natural harmful effects). This is also a frequently used pre-treatment in wood gasification, or for processing wood into briquettes, panels and similar products.  

Applications Of The Sawdust Rotary Dryer

Sawdust Rotary Dryer have many applications but are most commonly seen in the mineral industry for drying sands, limestone, stones and soil, ores, fertilizers, wood chips, coal, iron sulphate, filter cakes, sewage sludge, etc

 

Drum or Shell Variations Of The Sawdust Rotary Dryer

A Sawdust Rotary Dryer can consist of a single shell or many, though any more than three drums is not usually necessary. Multiple drums can reduce the amount of space that the equipment consumes. Multi-shell dryers consist of several concentric tubes. Multiple shells allow the dryer to be utilized in a more compact space. The drums are often heated directly by oil or gas burners. The addition of a combustion chamber on the entry end helps ensure efficient fuel usage, and that homogenous drying air temperatures. As the material moves through the rotating drum is heated and moisture released. Some dryers also offer the option to cool, clean, shred, and/or separate the dried material.
