 WORKING PRINCIPLE
Rotary Drum Drier is a kind of dryer with rotating cylinder body which is a little bit incline. The wet material is loaded from
one end from the screw material adding device continuously, and is stirred by the bafflers that are uniformly distributed in the barrel.The material is uniformly distributed and dispersed in the dryer and fully contacts the hot air of counter flow. When the material passing through the cylinder inside surface, it will contact with the hot air circling inside and being dried .Most of the dried product will be discharged from the other end of the dryer. Small part of the fine granule goes into the cyclone separator with the exhaust air. The powder will be separated and collected, and the exhausted air will be ejected to the atmosphere. During the drying course, the material will slowly move to the lower end from the higher part recur to the slowness rotating of the cylinder

APPLICATION

This dryer widely used in the following industries:

- Drying large particles and heavy material for chemical, mining, metallurgy and other industries, such as: mining, blast furnace slag, coal, metal powder, fertilizer, ammonium sulfate.
- Drying powder or granular materials which have special requirements, such as: HP vesicant, lees residue, precipitated calcium carbonate, activated clay, magnetic powder, graphite, dregs.
- Drying the material which required low-temperature and continuous drying process.

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.
