The main body of the rotary dryer is a slightly tilted and rotatable cylinder. The wet material is added from the top left, through the interior of the cylinder, and is effectively dried by contact with the hot air or the heating wall in the cylinder, the dried product comes out from the lower right. In the drying process, rely on the slow rotation of the cylinder, the material under the action of gravity from the higher end to the lower end of the move. The heat source used in the drying process is usually hot air, flue gas or water vapor. Rotary dryer is the oldest drying equipment， it is still widely used in metallurgy, building materials, chemical and other fields.
The characteristics of the rotary dryer:
1. High production capacity, less fuel consumption, low drying cost
2. Simple structure, easy to operate
3. Less trouble, low maintenance costs, easy to clean
4. Applicable to a wide range, you can use it to dry granular materials, can also be used for those materials with large adhesion
5. Operation flexibility, the production of products to allow the production of a larger range of fluctuations, will not affect the quality of the product
Rotary dryer has many advantages, mainly reflected in its stable performance, low energy consumption, a wide range of applications. Rotary dryer has a number of dry areas, a number of drying area not only increased the drying efficiency, but also to achieve energy saving.
Zhongzhou company convened several experts for the current industry market conditions, through repeated research and practice, carefully build the fifth generation of rotary dryer. The rotary dryer function is more powerful than the traditional dryer, the performance is more stable, the operation is more simple, the drying time is shorter.
Rotary dryer has the following applications:
1. It can handle the tailings produced by the various metal mines in the dressing industry and dry the slag.
2. It can dry the non-sensitive materials in the chemical industry.
3. It can dry the building's cement, limestone, sand, clay and other materials.
4. It can dry slime, coal, mixed coal, selected coal and other raw materials.
