1100°C Dual Zone Rotary Tube Furnace with Automatic Feeding and Collection System for Continuous Powder Processing

Product Overview

This high-performance thermal processing system represents a significant advancement in continuous materials synthesis, specifically engineered for the precise sintering and analysis of granular and powder-based materials. By combining dual-zone temperature control with a dynamic rotary environment, this equipment provides a seamless workflow from automated raw material input to the collection of processed products. The system is designed to eliminate the limitations of static batch processing, offering a level of throughput and heating uniformity that is essential for modern material science and high-end industrial R&D. Whether operating under a controlled atmosphere or high vacuum, the furnace ensures that every particle is exposed to consistent thermal conditions, which is crucial for achieving high-purity results in sensitive chemical reactions and phase transformations.

Primarily utilized in universities, national research institutes, and private industrial laboratories, this system excels in the demanding fields of energy storage and advanced metallurgy. It is the ideal solution for processing lithium-ion battery cathode and anode materials, as well as non-corrosive powders that require exact temperature profiles and meticulous handling. The industrial-grade construction allows for researchers to scale their chemical processes from initial development to pilot-scale production with high confidence. By automating the feeding and collection stages, the equipment minimizes human intervention, reduces the risk of contamination, and significantly increases the repeatability of complex multi-stage thermal cycles.

Reliability and operational safety are the cornerstones of this unit's design architecture. Built with a double-shell casing and secondary cooling fans, the external chassis remains safe to the touch even during prolonged high-temperature operations. The high-purity alumina fibrous insulation is selected for its superior energy-saving properties and thermal stability, preventing degradation during rapid heating and cooling cycles. This equipment is not merely a tool but a robust platform designed to withstand the rigors of intensive laboratory use, ensuring that researchers can focus on their material innovations without concern for hardware failure or inconsistent thermal performance. Every component, from the DC-driven rotation motor to the PID microprocessor, is integrated to deliver a stable, predictable, and high-performance sintering environment.

Key Features

• Advanced Dual-Zone Precision Heating: Featuring two independently controlled heating zones, this furnace allows for the creation of complex temperature gradients or extended uniform heat zones. Each zone is managed by an individual digital PID controller, ensuring that specific thermal profiles required for multi-stage chemical reactions can be maintained with an accuracy of ±1°C.
• Continuous Automatic Feed and Collection: This system is equipped with a high-capacity 500 ml automatic feeder and a 50 ml KF40 stainless steel collection tank. The integrated auger-driven feeder supports adjustable feeding rates from 3 to 60 ml/min, enabling precise control over material dwell time and throughput for industrial-grade continuous processing.
• Dynamic Rotary Mixing with Internal Vanes: The special-shaped quartz tube is designed with internal lifting vanes that cause powders to tumble and mix continuously as the tube rotates. This dynamic motion prevents powder stacking, eliminates internal temperature gradients, and ensures that the reaction atmosphere reaches every particle surface for complete and uniform sintering.
• Variable Speed and Tilting Capabilities: To control the flow rate and residence time of materials, the furnace features a DC motor-driven rotation (2–10 rpm) and an adjustable tilting mechanism (-5° to +20°). This flexibility allows operators to fine-tune the system according to the unique flow characteristics of various granular or crystalline materials.
• Atmosphere and Vacuum Optimized Sealing: Utilizing a sophisticated ferrofluid seal assembly and quick-clamp flanges, the equipment maintains vacuum integrity even during active rotation. This allows for sensitive materials to be processed under high vacuum up to 1000°C or under inert gas atmospheres, preventing oxidation and ensuring material purity.
• Rapid Cooling Split-Cover Design: The hinged split-cover construction facilitates easy access to the quartz tube for maintenance and enables significantly faster cooling between runs. Combined with the triple cooling fan system, this feature reduces downtime and allows for higher daily laboratory throughput.
• Sophisticated 50-Segment PID Control: The dual controllers offer a 50-segment programmable interface, allowing for complex heating, soaking, and cooling ramps. This automation ensures that once a recipe is established, the system delivers identical thermal conditions every time, which is critical for the graphitization and structural ordering of advanced catalysts.
• Industrial Resilience and Safety: The unit is housed in a robust double-shell casing with integrated safety features including mechanical pressure gauges, ball-valve gas outlets, and over-temperature alarms. The design ensures high thermal efficiency and complies with rigorous international safety standards, making it suitable for high-stakes industrial environments.
