5 Inch Rotary Tube Furnace with Automatic Feeding and Receiving System 1200C Three Zone CVD Powder Processing

Product Overview

This advanced rotary tube furnace system is engineered for the high-precision thermal processing of granular materials and powders under controlled atmospheric or vacuum conditions. By integrating a large 5-inch diameter quartz processing tube with an automated material handling workflow, the equipment provides a turnkey solution for researchers and manufacturers developing next-generation energy storage materials. The core value proposition lies in its ability to facilitate continuous chemical vapor deposition (CVD) and calcination while maintaining strict purity standards and thermal uniformity across a multi-zone heating environment.

The system is specifically optimized for the synthesis of lithium-ion battery cathode and anode materials, including lithium iron phosphate (LiFePO3), lithium manganese nickel oxide (LiMnNiO3), and silicon-carbon (Si/C) composites. In these demanding applications, the ability to process powders in a rotating environment ensures that every particle is uniformly exposed to the heat source and precursor gases, preventing the localized overheating or inconsistent reactions common in static bed furnaces. This makes the unit an indispensable tool for material science labs and industrial pilot lines focusing on scalable material synthesis.

Built for long-term reliability in rigorous industrial R&D environments, the equipment features a heavy-duty double-shell construction with integrated cooling fans to maintain a safe exterior temperature. The modular design, comprising a tiltable furnace body and a high-torque drive system, ensures consistent performance even when processing high-density powders. This system offers the durability required for 24/7 operation, providing the consistency and precision necessary to move complex chemical processes from the laboratory bench to larger-scale production with confidence.

Key Features

• Intelligent Three-Zone Thermal Architecture: The heating chamber is divided into three independently controlled zones (150mm, 300mm, and 150mm) totaling a 600mm heating length. This configuration allows for the creation of precise thermal gradients or an extended 450mm constant temperature zone within ±2ºC, ensuring uniform particle treatment throughout the processing cycle.
• Integrated Automatic Feeding and Receiving: Equipped with a precision volumetric powder feeder and a hermetically sealed 1-liter collection tank, the system enables continuous operation. The vacuum-sealed swivel assembly ensures that material enters and leaves the hot zone without exposure to ambient air, preserving chemical purity and moisture-sensitive characteristics.
• Precision Variable Speed Rotation: The high-torque DC gear motor allows for rotation speeds from 1 to 10 RPM. This tumbling action is critical for preventing powder agglomeration and ensuring that gas-solid reactions, such as carbon coating or reduction, occur uniformly across the entire surface area of the material.
• Electrically Actuated Tilting Mechanism: The furnace body can be tilted from -5° to +20° via an electric drive. By adjusting the tilt angle in conjunction with the rotation speed, operators can precisely control the residence time (dwell time) of the powder as it travels through the heated quartz tube.
• Advanced Vacuum and Atmosphere Control: Designed for operation under vacuum or controlled gas environments, the system features stainless steel sealing flanges with needle valves. A KF40 butterfly valve on the receiving system allows for the unloading of processed materials while maintaining a hermetic seal, protecting sensitive powders from oxidation.
• Split Cover Engineering for Rapid Cooling: The furnace features a split-shell design that can be opened easily. This allows for rapid cooling of the processing tube after a cycle, significantly increasing throughput and facilitating easy access for tube cleaning or replacement.
• Superior Thermal Insulation: High-purity alumina fibrous insulation is utilized to maximize energy efficiency and ensure rapid heating rates. This premium insulation material minimizes heat loss and contributes to the excellent temperature stability required for sensitive material synthesis.
• Safety-First Construction: The double-shell casing is equipped with three high-efficiency cooling fans to keep the outer surface cool to the touch. The system is designed to operate safely under low pressure (<3 psig), with integrated safety valves to prevent over-pressurization during gas delivery.
• Digital Command and Control: Each heating zone is managed by an individual PID digital temperature controller with 30 programmable segments. An optional RS485 port and Labview-based software allow for remote monitoring, data logging, and complex recipe management from a workstation.

Why Choose TU-X06

• Unmatched Process Uniformity: Unlike static furnaces, the rotary action of the TU-X06 ensures every gram of material receives identical thermal and chemical exposure, which is critical for the reproducibility of high-performance battery powders.
• Superior Automated Workflow: The integrated vacuum-sealed feeding and receiving system allows for continuous pilot-scale production without compromising the inert atmosphere or risking environmental contamination of the sample.
• Precision Multi-Zone Control: Independent control of three separate heating zones allows for the implementation of complex temperature profiles, such as pre-heating, reaction, and controlled cooling zones within a single pass.
• Robust Engineering for High Throughput: With a large 5-inch diameter tube and 10Nm of torque, this system handles higher material volumes than standard lab rotaries, bridging the gap between R&D and commercial scale-up.
• Expert Customization and Support: We provide comprehensive configuration options, including alternative tube materials for specific chemistries and integrated multi-channel gas delivery systems for advanced CVD applications.
