Detailed structure of rotary dryer

A rotary dryer is a commonly used industrial drying equipment that is used for drying bulk materials, such as minerals, fertilizer, grains, and chemicals. It comprises a cylindrical shell that rotates around its longitudinal axis, and the material to be dried is fed into the top of the cylinder. The shell is equipped with internal lifting flights to facilitate the movement of the material through the cylinder. Here is a detailed structure of rotary dryers and its table of specifications.

Structure:

1. Cylinder: This is the main body of the dryer, which is made up of a long cylindrical shell typically made of steel and lined with heat-resistant material.

2. Tire: The cylinder is supported using two or four tires that are mounted on girth gear at both ends.

3. Inlet and Outlet: The material to be dried enters through an inlet chute, while the dried material is discharged from an outlet.

4. End Seals: End seals keep the materials from exiting the cylinder other than through the outlet.

5. Lifting Flights: These are internal lifts that are attached to the cylinder lining to carry the materials throughout the cylinder while drying.

6. Burner: An external burner that is attached at one end of the cylinder provides hot gas to the dryer to dry the material.

Table of Specifications:

The table of specifications for a rotary dryer includes several key factors and features. These include:

1. Capacity - The maximum amount of material that can be dried per hour or per batch.

2. Operating temperature - The maximum and minimum operational temperature of the dryer.

3. Heating method - The type of heating method used, such as gas, oil, or electricity.

4. Moisture content - The moisture content of the material entering and leaving the dryer.

5. Rotary speed - The speed at which the cylinder rotates.

6. Burner power - The power of the burner used for heating.

7. Overall dimensions - The height, width, and length of the dryer.

8. Weight - The weight of the dryer.

By consulting the table of specifications, users can select the appropriate model and configuration based on their specific material and operational requirements, ensuring optimal performance and efficiency.
