China Slime Coal Rotary Dryer

Slime Coal Rotary Dryer

1--Coal Rotary Dryer Introduction
Coal 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 dry temperature ( generally 250-350°C).
2--Coal Rotary Dryer Application
1) Coal Rotary Dryer is suitable to dry metallic and nonmetallic mineral, clay in cement industry and coal slime in coal mine, etc.
2) Coal Rotary Dryer can be widely used to dry various materials and it is simple to be operated.
3) Coal Rotary Dryer is mainly used in building materials, metallurgy, and chemical industry, cement plant for drying of limestone slag, coal powder, slag, and clay stone.
3--Coal Rotary Dryer Structure
1) Coal Rotary dryer is formed by rotary body, lifting blade, driving device, supporting device and sealing ring.
2) Coal Rotary dryer 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.
4--Coal Rotary Dryer Working Principle
Coal Rotary Dryer adopts direct flow type of heating with heat soure from firing unit. The material to be dried is pushed back immediately 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.
