Rotary drum drier

1. Introduction of Rotary drum drier

Rotary drum drier 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 drier's feeding end can be indicated by the thermometer to control the inner drier temperature ( generally 250-350°C).

2. Application of Rotary drum drier

1).Rotary drum drier is suitable to dry metallic and nonmetallic mineral, clay in cement industry and coal slime in coal mine, etc.

2).Rotary drum drier can be widely used to dry various materials and it is simple to be operated.

3).Rotary drum drier is mainly used in building materials, metallurgy, and chemical industry, cement plant for drying of limestone slag, coal powder, slag, and clay stone.

3. Structure of Rotary drum drier

1).Rotary drum drier is formed by rotary body, lifting blade, driving device, supporting device and sealing ring.

2).Rotary drum drier 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. Working Principle of Rotary drum drier

Rotary drum drier 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.
