China Wood Chip Sawdust Rotary Dryer

Wood chip sawdust rotary dryer1.Sawdust Dryer IntroductionSawdust Dryer is widely used for drying materials in the industries of cemet, mine, contruction, chemical, food, compoud fertilizer, etc. Feeding and discharging unit is installed with thermocouple to control drier temperature. The temperature change of drier's feeding end can be indicated by the thermometer to control the inner drier temperature ( generally 250-350°C).
2. Sawdust Dryer Application1) Sawdust Dryer is suitable to dry metallic and nonmetallic mineral, clay in cement industry and coal slime in coal mine, etc.
2) Sawdust Dryer can be widely used to dry various materials and it is simple to be operated.
3) Sawdust Dryer is mainly used in building materials, metallurgy, and chemical industry, cement plant for drying of limestone slag, coal powder, slag, and clay stone.
3. Sawdust dryer Principle
Hongke Sawdust rotary dryer is mainly composed of cylinder, under frame, feeding and discharging devices, transmission device, gear cover, etc. (Optional auxiliary equipment includes combustion chamber, feeder and discharging device, and dust collection equipment). Rotary drier manufactured by us adopts new lifting plate, which is of functions like guiding, current-sharing, and material rising. The materials are raised and evenly drop so that they are in full contact with heat for better drying efficiency.
4. Sawdust Dryer Structure1) Sawdust Dryer is formed by rotary body, lifting blade, driving device, supporting device and sealing ring.
2) Sawdust Dryer is mainly composed of shell, back and forth supporting wheel, feeding and discharging unit and gear cap. The accessories which are not in the the scope of this machine include firebox, feeding and discharging equipment, dust catcher, etc.
5. Sawdust Dryer Working PrincipleSawdust Dryer adopts direct flow type of heating with heat soure from firing unit. The material to be dried is pushed back immediately by spiral board when enters the shell from feeding tank and feeding chute. Because the drier is installed in slope, material flows to the back end under gravity and rotation force, meanwhile, it is lifted by board repeatedly and thrown down accordingly, which make the material form even curtain, and exchange heat sufficiently with inner the heat flow. In the end, water in the material is dried by repeatedly scattering.6. Sawdust Dryer Main Technical Parameter
