Product Description
Brief Introduction:
The rotary dryer/calciner is a type of rotary kiln that employs indirect/direct 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. Many fins are welded onto the internal
wall of the rotary drum and the external wall of the rotating pipe, 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 an induced
draft fan or natural ventilation. Refering to organic solvents, an airtight steam heating rotary calciner can be
employed to recover these solvents. The presence of an internal circulating inactive gas or noble gas prevents
any potential explosions in the drying process.
Performance:
1. With a large heat transfer area, the thermal efficiency can reach 80 to 90 percent.
2. Suitable for continuous operation.
3. The dehydration process operates at low temperatures, making it user-friendly.
4. Mimimal gas requirement; gas only serves as a carrier for volatile components, and a simple dust collector is sufficient.
5. The airtight calciner is highly suitable for recovering organic solvents.
Technical specification:
Suitable materials:
1. Drying, heat treatment and calcining to powdery, granular material.
2. Nanometer, granular, and bulk materials.
3. Minerals and plants.
