Overview

Rotary sand dryer is widely used for drying materials in the industries of cement, mine, construction, chemical, food, compound 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 350-380°C).

 

Structure

Rotary sand 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).

 

Working Principle

Rotary sand dryer adopts direct flow type of heating with heat source 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.
