What properties the rotary dryer have?

1. With high thermal efficiency, energy-saving of rotary dryer is obvious. the thermal efficiency is around 50 times more than the traditional single cylinder according to the test. The effect of coal saving is obvious after the operation of the rotary dryer.　　

2. Drying mechanism is scientific, reasonable, efficient and energy saving. The material in the cylinder and the hot gas flow conduct the heat exchange in the form of radiation, convection and conduction, while the heat exchange outside cylinder are in the form conduction and convection at the same time.

3. The shortened length of the machine is advantageous for the process layout. The whole length of the machine is around 40*/shorter than that the single cylinder dryer, thereby reducing the construction area of the plant, saving the investment, and also more suitable for the process layout of the old factory.

4. This machine adopts the downstream drying process of the material and hot air flow，with a wide range of combination. It can adapt to the drying of raw materials such as clay, coal, slag, iron, etc., also applies to bulk materials drying of the metallurgical, chemical, etc..

5. The machine is compact in structure. The machine is in the horizontal layout with a riding wheel supporting. It adopts the riding wheel drive not the gear and pinion drive, therefore more convenient and manipulate for installation, more simple and reliable for operation and with higher operation rate.

6. Automatic temperature monitoring system makes the operation more convenient.　

7. A variety of lifting plate design, a combination between the angle lifting plate and words lifting plate make the material and the hot flue gas exchange fully, reduce the "wind tunnel" mechanism of dryer cylinder.  

8. It adopts the frequency speed adjustment, adjusting the speed of the cylinder body. It adopts the appropriate speed to ensure the requirements of the next process according to the requirement of water and output.

9. The external surface area is above 30% less than the single tube rotary dryer. the outer cylinder has the thermal insulation effect to the outer cylinder. With the low surface temperature and less heat loss, it’s with the high efficiency and energy saving. Meanwhile, it has greatly improved the working environment and working conditions.
