Product Description

Three Cylinder Rotary Dryer For Sand,River Sand 

 
Investment of Three cylinders rotary  dryer:
Low consumption, adpot the alloy steel plate whose abrasion resistance is 3-4 times than common steel plate, but the investment is 1/6 of foreign brand.
 
Work condition of Three cylinders rotary  dryer:
 
The material initial moisture is 15%, final is below 0.5-1.0%, is the first choice for the slag in the cement factories and premixed dry mortar production line.
The material granular size is around 20-40mm.



Three cylinder rotary dryer working principle :

Materials enter the inner side of the drum through the feeding device to realize current flow drying process, then the materials enter the middle layer of the inner wall through the other end to realize counter current drying process. They are lifted in over and over in the middle layer which advance in two-steps forward and one-step back way.

 

 three pass rotary dryer absorb heat from both inner drum and middle drum, which extend the drying time and realize the best drying condition. Finally, materials fall into the external layer of the drum from the other end of the middle layer, processing in a rectangle multi-loop way. The dried materials move quickly out of the drum under the hot air, while the wet ones remain because of their own weight. Materials are dried completely inside the rectangle shoveling plate and then cooled by the single drum cooler, thus finishing the whole drying process.

Three cylinder rotary dryer structure:




Installation and practice of Three cylinders rotary  dryer:
Compared with single cylinder dryer, reduce about 50% area, the groundwork consumption reduce a half. The whole equipments have no leakage, can finish the installation in 2 hours, and easy to pratice in following period.
