Lignite Dryer       


Product Description:
Adopting new technology of first crush and then thermal drying lignite, Rotary lignite dryer makes drying process continuous, industrialized and automatic.
In the condition of ensure the mass of dried lignite invariant, rotary lignite dryer adopts low-temperature four grades drying dehydration process. Moisture of dried lignite can be less than 13%. Feed material in first drying area. In high humidity, heat transfer between material and high temperature negative pressure air proceeds when the the inlet temperature is 600 ° C. It can remove most of the water, and difficult to catch fire. Eliminate bond in the second drying area. Indoor temperature is 450 ° C. Downstream drying proceeds in the third drying area. Indoor temperature is 300 ° C. High drainage proceeds in the fourth drying area. Indoor temperature is 100 ° C. The whole process is low-temperature drying, difficult to cause slime combustion. It is energy saving and consumption reducing.
1. Inclination of stock guide in feeding device is increased, makes wet lignite enter strengthen drying process quickly.
2. Length of lifter blade in the front section of dryer is increased to prevent adhesions.
3. Contact between material and hot flue gas and the time they stay in dryer cylinder are increased.
4. Cleaning and thermal conduction effects are strengthened. It can effectively prevent material cementation around lifting plate and inside wall of cylinder wall. In addition, it also has unique crushing device and automatic cleaning device.
5. Operating parameters can be changed depending on the material properties. It makes the material form a stable full section materials curtain in dryer cylinder and mass and heat exchange fully.
6. Large handling capacity, low fuel consumption and cost.
7. Heat-resistant paint on the surface of dryer will not fall off in the operation process.
8. Dryer for coal slime greatly reduces wear of riding wheel, make cylinder operate smooth and reliably.
9. Self-aligning riding wheel device makes riding wheel and rolling ring linear contact forever, thereby greatly reduce wear and power loss.
10. New type feeding and discharging devices eliminate blocking, returning, discontinuous and uneven of materials in cylinder dryer, reduce load of dust pelletizing system.
