Most Popular Rotary Drum Dryer for coal slime

Part one--Introduction of Coal Slime Rotary Dryer

Dryer 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).

Part two--Working principle

1. Drying process needs to consume large amount of heat energy. In order to save energy, some materials with high moisture content, suspending liquid and solution which contain solid objects should be mechanically dewatered or heated first, and then they can be dried in a dryer to get dry solids.

2. During drying process, heat and weight (moisture content) transfer need to be finished simultaneously, thus guaranteeing a higher moisture and water vapor partial pressure inside the dryer than that outside the dryer, and guaranteeing a higher temperature of heat source than that of materials.

Part three--Features

1. Coal Slime dryer can be heated direct or indirect, the heating efficience can be up to 95%.
2. Coal Slime dryer operating under high temperature and low oxygen to avoid materials being self burning or exploding when drying. Big drying capacity, highly industrilization and low cost.
3. sterillization
4. low amount of air required to save tail gas handling cost.
5. Rotating part rotates slowly, low abrasion wear.
6. Firm construction, durable.
7. compact structure, big heating area, smaller installation area .

Part four--Structure of Coal Slime Rotary Dryer

1) Coal Slime Rotary Dryer Machine is formed by rotary body, lifting blade, driving device, supporting device and sealing ring.

2) Coal Slime Rotary Dryer Machine 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.
