Introduction of Rotary Dryer

Rotary dryer can dry many kinds of materials which contain moisture, such as coal, coal slurry, slag, industrial waste, and clay stone. Rotary dryer are widely used in building materials,metallurgy, and chemical industry. Rotary dryer is handling by bringing it into direct contact with a heated gas. The dryer is made up of a large, rotating cylindrical tube,the dryer slopes slightly so that the discharge end is lower than the material feed end in order to convey the material through the dryer under.

Working Principle of Rotary Dryer

The rotary dryer uses the sleeve sets out the structure can be doubled to reduce the length of the dryer, due to significant reduction of the cooling surface, resulting in decreased heat consumption, while doubling the heat exchange surface to greatly enhance thermal efficiency. Materials that can not touch tobacco, multi-drum rotary dryer provided in the inside and outside the cylinder, respectively, within the smoke pipe and circular pipe, the flue pipe of communication between the radial, the same energy efficient. It is obvious that on the hot and cold media in terms of material, this machine a sleeve-type rotary cooler.

Advantages of Rotary Dryer

 The rotary dryer is mainly composed by the revolving body, lifting plate, driving device, supporting device, sealing ring and other components.

--big processing capacity,

--simple maintenance,

--long service life,

--reasonable structure,

--high efficiency,

--low energy consumption.

Performance Characteristics of Rotary Dryer

1. Rotary dryer,high thermal efficiency,energy saving effect is obvious,the thermal efficiency considerably more than the traditional single drum dryer;

2. The machine length shortening,is helpful to process arrangement.Than the single cylinder dryer machine length shortened about 40%, and reduce the construction area of factory building,save construction investment,also more suitable for old plant modification process arrangement;

3. The machine's external surface area than the single tube rotary dryer is reduced by more than 30%,the external and internal cylinder has heat preservation and heat insulation effect,outer tube surface temperature is low,less heat loss,at the same time of high efficiency and energy saving,greatly improve the working environment and working conditions;

4. This machine structure is compact.Level of the whole machine layout,using roller bearing,cancelled size gear transmission,instead of riding wheel transmission,makes the convenience of the equipment installation,manipulation,more simple,more reliable operation and operation rate is higher;

5. A variety of feed plate design,Angle feed plate with a swastika feed organic combination,make the material with hot flue gas exchange more fully,reduce the production mechanism of the dryer cylinder body "wind tunnel";

6. Adopts frequency control of motor speed,adjust the dryer cylinder speed equipment,according to the water into the machine, production requirements,adopting the appropriate speed,to ensure the demand of next working procedure;

7. The automatic temperature monitoring and control system,make the operation more convenient.
