What is the difference between a rotary tube furnace and a rotary kiln?
The main differences between rotary tube furnaces and rotary kilns are as follows:
1. Structure and size
- Rotary tube furnaces usually have smaller size and relatively simple structure, mainly composed of tubular furnace, heating elements, rotating device, etc.
- Rotary kilns are generally larger in size and more complex in structure, including long cylindrical kiln body, support device, transmission system, sealing device, etc.
2. Application field
- Rotary tube furnaces are often used for small-scale material processing, chemical experiments, sample firing, etc. in laboratories.
- Rotary kilns are mainly used for large-scale industrial production, such as cement production, ore roasting in metallurgical industry, material calcination in chemical industry, etc.
3. Processing amount of materials
- The amount of materials processed by rotary tube furnaces is relatively small.
- Rotary kilns can process large amounts of materials to meet the needs of industrial production.
4. Temperature and atmosphere control
- The temperature control of rotary tube furnaces is usually more precise, and atmosphere control is relatively easy to achieve a variety of conditions.
- Rotary kilns may present challenges in terms of uniformity and precise control of temperature and atmosphere due to their large scale and complex structure.
5. Operation mode
- The rotation speed and operation mode of a rotary tube furnace are relatively flexible and can be adjusted according to experimental needs.
- The operation of a rotary kiln is usually continuous and stable to ensure the continuity and stability of large-scale production.
6. Cost
- Rotary tube furnaces are generally low-cost and suitable for small-scale research and experiments.
- Rotary kilns are expensive due to their large scale, complex structure and high power requirements.
