1200°C Rotary Tube Furnace with Automatic Material Collection System

Laboratory Rotary Tilting Tube Furnace with Automatic Material Collection System

The Rotary Tilting Tube Furnace for Processes with Continuous Movement up to 1200°C is a laboratory and pilot-scale thermal processing system designed for the continuous movement, heating, sintering, calcination, reduction, and heat treatment of powder and granular materials.

The furnace combines continuous tube rotation with an adjustable tilting structure, allowing materials to continuously tumble and move through the heated zone during processing. This dynamic material movement improves heat transfer and gas-solid contact, helping achieve more uniform thermal treatment compared with conventional static tube furnaces.

Rotary Tilting Tube Furnace for Processes with Continuous Movement up to 1200°C

Introduction:

An automatic material collection system is installed at the discharge end of the furnace tube, allowing the processed material to be collected conveniently after passing through the heated zone.

The furnace can be used for a variety of advanced material applications, including lithium battery materials, rare earth materials, chemical catalysts, magnetic materials, powder metallurgy, ceramic powders, and hydrogen reduction processes.

Key Features:

1. Rotary and Rocking Motion for Uniform Heat Treatment

The reaction tube continuously rotates and oscillates during operation, causing powder materials to tumble in both radial and axial directions. This movement helps improve material mixing, temperature uniformity, and contact between the powder and process gas.

Compared with conventional static sintering, the rotary rocking design can help reduce problems associated with uneven heating, localized overheating, over-sintering, or incomplete sintering.

2. Adjustable Tilting Angle

The furnace body can be tilted from -5° to 30°, allowing users to adjust the material movement and residence behavior inside the tube.

The tilting design also makes material loading and unloading easier, improving operational convenience for laboratory and pilot-scale powder processing.

3. High-Purity Quartz Reaction Tube

The furnace is equipped with a high-purity quartz tube suitable for high-temperature laboratory applications. An embedded lifting scraper structure helps continuously lift and turn the powder during tube rotation, supporting more uniform exposure to heat and process gases.

4. Excellent Thermal Insulation and Energy Efficiency

The furnace chamber uses high-purity Al₂O₃ ceramic fiber insulation, providing excellent thermal insulation performance and reduced heat loss.

This lightweight insulation structure helps improve heating efficiency and reduce overall power consumption.

5. Vacuum and Controlled Atmosphere Capability

An advanced dynamic sealing system allows the rotary tube furnace to operate under controlled process conditions, including:

Vacuum
Air
Nitrogen
Argon
Hydrogen or reducing atmospheres
Other customized process gases

This makes the furnace suitable for a wide range of powder sintering, calcination, reduction, and atmosphere heat treatment applications.

6. Fully Automatic Control System

The system features a fully automatic control system with a 7-inch touchscreen interface.

Users can monitor and control important operating parameters in real time, including:

Furnace temperature
Heating program
Tube rotation
Rocking operation
Furnace tilting angle
Process status
Gas and vacuum system status

The programmable control system provides improved repeatability and convenience for laboratory research and pilot-scale production.
