Introduction of rotatry dryer machine
Sawdust dryer with heating furnace, feed port, rotating cylinder, delivery pipe, dust collector and discharge port. Wet material is continuously sent to the drying cylinder by a conveyor. Heat air makes full contact with the material. Being delivered and scattered by the high-speed hot air, water in the wet material is evaporated. The material gets fully dried in the rotating cylinder.
Sawdust dryer is widely used in industries like biomass fuel, charcoal making, wood pellet fuel, sawdust briquette, farming and sand etc. The applicable materials are wood powder, wood shavings, sawdust, wood chipps, straws, grass, sand, etc
Application of rotatry dryer machine
Sawdust dryer of rotary drum type is widely used in industries like straw briquette fuel, charcoal machinery, wood pellet fuel, sawdust briquette, farming and animal husbandry engineering etc. such as the drying of agricultural fiber materials like maize straw, soybean straw, cotton straw, wheat straw, sorghum stalk, wood powder, wood shavings, sawdust, ginkgo leaves, mulberry leaves etc.
Details of rotary dryer
The principle of the rotary drier is as follows,the hot air move forward from the tail,then full access with materials,through heat conduction,convection and radiation heat transfer,then deliver the heat to materials directly,then the materials moisture content is evaporated constantly in the cylinder body,the wind device on the outlet take out a large number of moisture,wet,to prevent the second pollution caused by the dust discharging.Through the spiral stirring and shovelling plate to drive the material moved,until finish the whole drying process.Flow counter conduction dry off the wet,avoid and reduce repeated drying process.
Technical details of the rotary dryer machine
Our sawdust rotary dryer machine is suitable for drying materials of moisture 20~50%. The rotary dryer machine is equipped with inlet, steel pipe, fan blower, air lock and cyclone.
Wet materials are put into the hopper. The fuel boiler generates hot air which mixes with wet materials and then is sucked into the pipes by the fan blower quickly. And then hot air is flowing and going though the curving pipes and buffer (drying chamber) of eco-friendly dryer, thus wet materials is finished to dry, and the dried materials are discharged from the outlet with air lock. This eco-friendly dryer reduces the moisture to 8~12% with the advantages of low cost consumption and high efficiency.
1.sawdust dryer /wood chips dryer mainly used in biomass pellet production line , dry the material , such as wood chips, sawdust, shaving or efb fibre or shells , other materials.
2. this is a rotary dryer machine , can dry the finished fertilizer pellet .
3. different model with various diameter and length , it means their evaporation is differenet . For the same model rotary dryer machine ,we also can control its evaporation scale . if humidity too large , we can adjust feeding speed and drum RPM lower to make longer drying time .
4. the working principle of dryer is the heat provided by stove go forward in the dryer 'barrel with the rotating of dryer barrel.
5.. the rotary dryer machine has two ways to discharge materials.
one is to outlet from rotary drum bottom, it is mainly fit for large weight ratio materials , the other is to outlet materials from cyclone bottom , which mainly fits for light ratio materials . On one hand with high drying efficiency , on the other hand clean dust.
The rotary dryer machine drying 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. Often, indirect heated dryers are used when product contamination is a concern.
rotary dryer machine Raw material:
Rotary dryer can dry many kinds of materials which contain moisture, such as coal, coal slurry, slag, industrial waste, and clay stone. Rotary dryer are widely used in building materials,metallurgy, and chemical industry. Rotary dryer 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.
