Zhengzhou Bangke Machinery Manufacturing Co.,Ltd. specialized in
the production of wood sawdust dryer for 20 years.Mainly used for
drying wood chips,sawdust and saw powder.Our company has good
service,reasonable price and get support by our customers.
Wood sawdust dryer continuously send the wet material to the rotary
body with the screw conveyor. In the high speed transmission and
dispersion of heat flow, the water in the wet material will be
evaporation and get powder or granular dry sawdust.The sawdust
dryer consist of air heater, feeder hopper, airflow drying tube,
cyclone separator and draught fan.
The application of wood sawdust dryer
The wood sawdust dryer is widely used in straw briquette fuel,
charcoal machinery, wood pellet fuel, sawdust briquette, farming
and animal husbandry engineering industry.For example corn stalk
drying, soybean straw drying, cotton stalk drying, wheat straw
drying, sorghum stalk drying, sawdust drying, shaving drying etc.
agricultural fiber materials drying.
The characteristics of wood sawdust dryer
Large intensity of drying.Due to the material in the air highly
fragmented, All the surface area of particles are the effective
area of drying.
The drying time is short.
Air dryer has simple structure, small floor coverage, easy
installation and maintenance.
Large capacity of material processing and high thermal
efficiency.When drying unbound water, thermal efficiency can reach
The working principle of wood sawdust dryer
The wood swdust dryer includes heating furnace, feeding hole,
rotating cylinder, filter cartridge, conveyor pipe, the cooling
tube and discharge hole. The rotating cylinder is on the drving
roller, the drving roller which transmitted by motor and reducion
drive the rotating cylinder rotation at low speed. Between the
heating furnace and rotating cylinder sets feeding device.In the
rotating cylinder has stirring blades.`The junction between
rotating cylinder and filter cartridge is equipped with baffle,the
baffle has a small hole One side of the filter cartridge is
connected with rotating cylinder,another side is linked with
As a result of the above structure, the sawdust can be fully drying
in the rotating cylinder, before entering the conveying pipe, the
sawdust can fully spread out again and make the moisture evaorates
quickly. The baffle can block the impurity in the sawdust, make
sure the sawdust quality which entered the conveying pipe.The
sawdust enter into the dryer under the common action of spary torch
and rotating cylinder,the material in the tube will flow
boiling,hot wind and material has a good contact and finished
dring. The utility model has the advantages of simple structure,
