Rotary dryer is widely used in the field of building materials, metallurgies, chemical industry, cement, Food processing industry and so on. It can dry slag, coal powder, mining powder, clay, sand, limestone, cassava ,wood sawdust,manure, fertilizer, and so on. It is made into rotary body, lifting blade, driving device, supporting device etc. The dryer has advantages of reasonable structure, high efficiency, low energy consumption and convenient for transportation.
2.Raw materials requirement of rotary drum dryer:
a. the size should be less than 20mm ;
b. the moisture should be 60%-70%,after drying can be 5%-10%;
3. The working princple of Rotary dryer:
Rotary dryer adopts direct flow type of heating with heat soure from firing unit. The material to be dried is pushed back immindiately 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.
