Three Cyclinder Rotary Sand Dryer Use Coal Fuel And Gas Fuel
Description of widely used rotary sand dryer:
Rotary dryer is widely used for drying materials in the industries of cement, mine, contruction, chemical, food, compoud fertilizer, etc. Feeding and discharging unit is installed with thermocouple to control drier temperature. The temperature change of drier's feeding end can be indicated by the thermometer to control the inner drier temperature (generally 250-350°C)
Features of rotary 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.
Structure of rotary dryer :
Rotary dryer is mainly composed of shell, back and forth supporting wheel, feeding and discharging unit and gear cap.
Application of rotary dryer:
Mineral industry: Bentonite, Titanium concentrate, coal, manganese ore, pyrite, limestone, peat
Chemical industry: ammonium sulfate, sodium sulphide, ammophos, ammonium nitrate, carbamide, oxalic acid, potassium dichromate, PVC, nitrophosphate fertilizer, calcium magnesium phosphate, compound fertilizer
Food industry: Glucose, salt, granulated sugar, vitamin malted milk, granular sugar
Others:Iron powder, flat soybean, garbage abrasive, match sticks, wood chips, vinasse
