Rotary Dryer Machine With Easy Operation System Sell In China
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
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
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
