Slag dryer is mainly used for drying materials with certain humidity in ore dressing, building materials, metallurgy, chemical industry, printing and other industries. Due to its strong adaptability, rotary dryer is capable of drying various materials, Moreover, it is easy to operate and stable, so it is commonly applied.
The usage of slag dryer:
Rotary dryert is widely used for drying materials in the industries of cemet, mine, contruction, chemical, food, compoud fertilizer, etc. Feeding and discharging unit is installed with thermocouple to control drier temperature. The temperature change of dryer's feeding end can be indicated by the thermometer to control the inner drier temperature ( generally 250-350° C)
The structure of slag dryer:
Rotary dryer machine is mainly composed of shell, back and forth supporting wheel, feeding and discharging unit and gear cap. The accessories which are not in the the scope of this machine include firebox, feeding and discharging equipment, dust catcher, etc.
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.
After the damp raw material is put into the drier from on end, it is turned over through strring-up rake inside the cylinder and distributed uniform in the drier and contacted with countercurrent hot air fully. It speeds up heat and mass conducting of dry. During the oeriod of dry, raw material is effcted by stirring-up rake with gradient and hot air, it can be moved and passed through the dry region and to star valve and then discharge the finished product.
Features of slag dryer
Compared with other dryers, rotary drying machine has the following features:
1) Large production capability, continuous operation.
2) Simple structure, convenient operation.
3) Low malfunction, low maintenance cost.
4) Wide scope of application. It can be used for drying granular materials, especially benefit for those materials with big adhesion.
5) Great operating flexibility. The production allows a larger fluctuation range in the output of products, but not influence the quality of product.
