Introduction of mining coal slime rotary dryer

Rotary dryer is widely used for drying materias 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 in inner drier temperature(generally 250-350 centigrade degrees).

Coal slime dryer machine special features:

1. By direct or indirect heating, the heating efficiency can be reach up to 95%

2. Operating under high temperature and low oxygen to avoid materials being self-burning or exploding when drying

3. Big drying capacity, highly industrialize and low cost

4. Low amount of air are required to save tail gas handling cost

5. Rotating part rotates slowly and low abrasion wear

6. Firm construction and durable

7. Compact structure, big heating area, and smaller installation area

Working Principle of coal slime dryer

It mainly consists of revolution body, raise material board, transmission device, supportive device and sealing ring, etc.

The heat sources of the drier is from the combustion train, and is adopts down-flow heating methods. When the materials enter into the body from the feeding device, it will be pushed back by the spire raising board. As the drier is in an inclined position, the materials will be down to the lower end under the influence of gravity and rotation, but the raising board will be threw to the upper end for scattering. This procession makes the material well-distributed in the body, and then ensure the heat exchange with the heat wind. After repeated cycle with this procession, the moisture content will be dried.
