Description

Brief introduction:

The rotary calciner/dryer is a type of rotary kiln that employs indirect heating.

How does it work?

Steam heating is one of the methods used for indirect heating. An internal steam heating pipe is positioned

across the rotary drum, which is concentric with the stationary drum. The heating pipe rotates along with

the rotary drum, ensuring that the material is continuously lifted, stirred, and heated by the pipe. Due to the

inclination of the drum, the desiccated material moves from the high end to the discharge gate at its low end.

The moisture content that vaporizes gets expelled through a draft fan or natural ventilation. In cases

involving organic solvents, an airtight steam heating rotary dryer/calciner can be employed to recover these

solvents. The presence of an internal circulating inactive gas prevents any potential explosions in this

dryer/calciner setup.

Performance:

1. With a large heat transfer area, the thermal efficiency can reach 80 to 90 percent.

2. Suitable for continuous operation.

3. The desiccation process operates at low temperatures, making it user-friendly.

4. Minimal gas requirement; gas only serves as a carrier for volatile components, and a simple dust collector is sufficient.

5. The airtight dryer is highly suitable for recovering organic solvents.

Technical specification of rotary dryer / calciner:

Suitable material for rotary dryer:

Rotary dryers are suitable for handling materials that require continuous drying, such as gypsum, HDPE,

TA/PTA, POM, melamine, chloroethylene, ABS resin, pentaerythritol and other organic compounds. They

are also used for copper, iron and nickel concentrates as well as sodium carbonate, potassium carbonate and

various types of feed and sludge.

Suitable material for rotary calciner:

1. Drying, heat treating, and calcining powdery and granular materials.

2. Nano, granular, and bulk materials.

3. Minerals and plants.
