Rotary Tube Tilt Furnace

A Rotary Tube Tilt Furnace is a highly specialized furnace engineered to deliver precise and consistent heat treatment for granules, powders, and other particulate materials. Unlike traditional static furnaces, this advanced system incorporates a rotating tube or reactor that can be tilted, offering superior heat distribution and seamless material handling. The rotary tube ensures that materials inside the furnace are constantly moving, which enhances thermal transfer and prevents agglomeration or uneven heating, making it ideal for processes that demand high temperature uniformity and efficiency.

This dynamic design allows the Rotary Tube Tilt Furnace to accommodate a wide range of particle sizes, shapes, and types of materials, from fine powders to coarse granules, making it a versatile tool for numerous industrial heat treatment processes such as sintering, calcination, and carbon activation. The continuous rotation ensures that each material particle is exposed to consistent temperatures, minimizing the risk of hot or cold spots, which is common in static furnaces and can lead to material defects or inconsistencies in the final product.

Additionally, the tilting capability of the furnace adds a critical layer of processing flexibility. By adjusting the angle of the furnace, operators can optimize the flow of materials, controlling residence times and processing speeds to meet specific requirements. This is particularly advantageous when dealing with bulk materials, ensuring smooth discharge, reduced material build-up, and improved operational efficiency. The combination of rotation and tilt makes Tempsens rotary tube furnace particularly suited for batch and continuous operations, providing excellent scalability for both pilot and large-scale production environments. Furthermore, the system can be integrated with advanced control technologies, allowing for precise management of temperature, atmosphere, and material flow, further enhancing its capabilities in high-performance industrial applications.

• Low RPM range 1-20 RPM : The low RPM is ideal for delicate materials, ensuring that they receive uniform heat exposure while preventing clumping or uneven thermal distribution. Additionally, it allows for precise control over the residence time of materials, making it suitable for both sensitive and robust heat treatment processes.
• ·Tilt angle 6-15°: This feature allows the operator to modify the flow rate of materials through the furnace by altering the gravitational effect on the materials within the tube.
• Gas purging & Vacuum atmosphere : The ability to switch between gas purging and vacuum operation provides significant flexibility, enabling the furnace to be used in applications such as sintering, calcination, and annealing.
• Continuous & batch production operation: This dual capability means the furnace can cater to both small-scale pilot testing and large-scale industrial production.
• Max. temperature 1200°C : This temperature range is sufficient for most industrial applications such as carbonization, ceramic sintering, catalyst activation, and material drying.
• Split mechanism for easy loading of tube: This user-friendly design reduces downtime and helps ensure smooth operation, particularly during frequent material changes.
• Tube material Quartz/alumina : The choice of tube material depends on the specific application, ensuring optimal performance based on process needs.
• Scraper bars tube for proper mixing, large diameter tube at centre: The Rotary Tube Tilt Furnace is equipped with scraper bars inside the tube to ensure proper mixing of materials during rotation. This feature prevents materials from sticking to the tube walls, enhances material agitation, and ensures uniform heat distribution throughout the process.
