2.  Definition of Rotary Dryer.  Characteristics of Rotary Dryer.  Best of Rotary Dryers.  Description of Rotary Dryer.  Construction of Rotary Dryer.  Rotary Dryer advantages and disadvantages.  Applications of Rotary Dryer.

3. Definition ;- Type of industrial dryer employed to reduce or minimize the liquid moisture content of the material by bringing it in direct contact with a heated gas.

4.  Specially designed lifting flights to maximize heat transfer between the material and hot gas stream.  Heavy duty design and construction for many years of service.  Process and Mechanical Warranties.  Rotary Dryers are suitable for drying a wide range of materials.  It can be widely used to dry various materials and it is simple to be operated.

5. Best in Class Rotary Dryers ;- All of our dryers are custom designed to suit the unique processing needs of your material. Whether you require low or high inlet temperatures, short or long residence times, counter-current or co-current flow.

6. It can be offer cost competitive designs for pilot scale units that process as little as one ton per hour to heavy duty units in excess of 17 foot in diameter that process hundreds of tons per hour.

7. A rotary dryer consist of a cylindrical shell, set with its axis at a right angle to the horizontal and mounted on rollers so that it can be rotated. The material to be dried is fed to the high end of the dryer and by rotation of the dryer, usually assisted by internal shelves of flight, is gradually advanced to the lower end where it is discharged. The source of heat for a rotary dryer is usually the hot air that circulates through the using dryer. Description ;-

11.  large production capacity, continuous operation.  simple structure, easy to operate; less failure, low maintenance costs.  a wide range of application, fluid resistance is small, you can use it to dry granule-like material, for those adhesion material, it is also very beneficial.  operating flexibility, production flow allows the product to have a greater fluctuation range, will not affect the quality of the product.  cleaning easy.

12.  the equipment is large, one-time investment are high.  the installation and removal are difficult.  the heat loss is large, thermal efficiency is low (steam tube rotary dryer thermal efficiency is high).  the material in the dryer stay a long time, the material granules residence time have large differences.

13. Applications ;- Rotary Dryers have many applications but are most commonly seen in the mineral industry for drying sands, limestone, stones and soil, ores, fertilizers, wood chips, coal Iron sulfate, filter cakes, sewage sludge.
