Description of Rotary Dryer:  

Rotary dryer, which is also called a rotary calcine kiln, is widely used in drying some materials.Rotary dryer is used for drying materials with humidity or granularity in the industries of mineral dressing, building material, metallurgy and chemical.The consumption of the coal and the electricity is lower than the common ones. While the production capacity is higher than 10-15%. 

Rotary dryer has advantages of reasonable structure, high efficiency, low energy consumption and convenient for transportation, and convenient and reliable operation; Therefore, the consumption of the coal and the electricity is lower than the common ones. While the production capacity is higher than 10-15%. 

Rotary dryer can be used in the chemical, metallurgical, and building industries for drying many kinds of materials limestone slag, coal powder ,clay stone, limestone and other materials with a certain level of humidity or granularity.

1. Working Principle : 

The raw material plate which is arranged reasonably with changeable angles in order, throws moisture materials into the rotary cylinder. Then water will be separated from the materials by hot air-flow and changed into vapour to be discharged into the atmosphere. Then the materials would be dried.

2. Composition-structure: 

Rotary Dryer is formed by rotary body, lifting blade, driving device, raw material feeding plate, supporting device and sealing ring,etc.
