Detailed Description
Desulfurization gypsum dryer working principle and application rang:
This equipment saves 1/3 energy compared with the traditional rotary drum dryer which reduces cost greatly. The working principle: Desulfurization gtypsum goes to the internal layer of the three-layer roller by way of feeding system to be dried in direct flow way. It is lifted by the internal layer shoveling plate repeatedly and disperses in a spiral shape to exchange heat. The material moves to the other end of the internal layer and enters into the medium layer for reverse flow drying where the material is made moving forward and back again and again in a station of moving forward two steps while backward one step. The material in the medium layer absorbs the heat from the inner layer of the roller as well as from the medium layer roller which prolongs the drying time and the material can be in the best drying station. The material drops to the outer layer when it comes to the end of the medium layer and moves in a rectangle multi-loop way. The one that qualified for the drying effect moves fast out of the roller under the hot wind. The one unqualified can not move as fast due to its self weight and will be dried fully in rectangle shoveling plate. Thus end the drying process. This equipment is applicable to the drying of gypsum and fly ash.
The main characteristics:
1. The dryer is of strong overload capacity resistance, large process load, low fuel consumption, and low cost.
2. It adopts direct flow drying method. The gas fume and the material go to the dryer from the same side. By using the hyperthermia gas fume, the evaporation strength is very high. With the low outlet temperature, the heat efficiency is very high.
3. The operating parameter can be changed according to different materials. So that the material can form a stable fabric curtain and achieve fully heat exchange.
4. The new type feeding and discharging device solve the problem of feeding jam, discontinuous and uneven feeding, and returning charge which lighten the load of dedusting system.
5. The zero level thrust of the dryer reduces the abrasion to the catch wheel and the riding wheel. The operation of the rotary drum is stable and reliable.
6. The dryer adopts the riding wheel device, which make the riding wheel and the rolling ring linear touch all the time. Thus the abrasive and the power loss are greatly reduced.
7. The moisture is adjustable according to the customer’s needs.
