This focus on reliability and performance makes the equipment an essential asset for manufacturers and researchers who require absolute precision in their thermal treatment workflows, providing the confidence needed for critical material development and quality-controlled production cycles.

Key Features

• Dual-System Continuous Feeding Infrastructure: The furnace is equipped with a versatile feeding assembly featuring both a 20L hopper and a massive 300L feeding bin. These two sets of exchangeable feeding systems allow operators to switch between different throughput requirements or material types effortlessly, facilitating long-duration, uninterrupted operation that is critical for industrial productivity.
• Dynamic Rotary Tube Agitation: The continuous rotation of the processing tube ensures that powder materials are constantly tumbled and mixed during the heating cycle. This dynamic movement prevents the "center heat lag" effect found in static furnaces, ensuring every particle is uniformly exposed to the heat source and process atmosphere for superior reaction kinetics.
• Adjustable Inclination for Residence Time Control: The furnace body features a precision tilting mechanism that allows the angle of the tube to be adjusted. This engineering feature enables operators to control the flow rate and residence time of the material through the heated zone, allowing for rapid discharge or prolonged soaking depending on the specific process requirements.
• High-Performance SS310 Processing Tube: Utilizing a 2700mm processing tube made from high-grade SS310 stainless steel, this system provides excellent oxidation and corrosion resistance at elevated temperatures. The customized tube specifications ensure the equipment can be tailored to match the volumetric and chemical needs of specific industrial powders.
• Advanced Multi-Zone PID Temperature Control: This system utilizes a sophisticated PID automatic controller capable of 30 programmable steps. This allows for complex heating profiles with a temperature accuracy of ±1°C, ensuring that even the most sensitive materials are processed within strict thermal tolerances for repeatable batch results.
• Integrated Atmosphere and Vacuum Management: To support advanced material synthesis, the furnace includes a comprehensive gas supply and vacuum system. This allows for processing under inert, reducing, or vacuum conditions, protecting sensitive powders from oxidation and enabling precise chemical reactions within the sealed rotary environment.
• High-Efficiency Ceramic Fiber Insulation: The furnace chamber is constructed using lightweight, high-purity ceramic fiber. This material choice minimizes heat loss, reduces energy consumption during the 55KW power cycles, and allows for faster heating and cooling rates, which enhances overall throughput and equipment efficiency.
• Robust Resistance Wire Heating Elements: The unit employs high-quality resistance wire heating elements designed for longevity and consistent heat distribution. These elements are strategically placed to provide a uniform temperature field across the extended 2700mm tube length, ensuring no cold spots interfere with material quality.
