What Is a Rotary Tube Furnace?

By definition, a rotary tube furnace is a heat treatment circular furnace that rotates during the heat treatment process. When the sample is heated, it is transported through the furnace in a circular path.

Rotary tube furnaces usually burn powder, solid, gas, or liquid fuel to their working section, and then heat the gas to produce a flow to the sample. These furnaces are characterized by a metal barrel lined with refractory material and installed at an angle.

Rotary tube furnaces are designed for the heating of loose materials in physical and chemical processing, and are classified according to their heat exchange method (parallel or reverse airflow) and energy transfer method (direct, indirect, or combined).

These furnaces are designed for continuous material processing because it heats the sample in multiple thermal control zones. The heat is transferred from the heat source to the rotating tube containing the sample.

Applications of rotary tube furnaces

Rotary tube furnaces have a wide range of applications. They can be used to make a variety of materials, including alumina, vermiculite, iron ore pellets, and cement clinker.

They can also be used for oxidation, that is, the increase of oxygen and the loss of electrons in the sample, and roasting, which is a process used to influence phase transitions.

We have rotating tube furnaces for various applications and industries.

The rotating tube assembly of these furnaces can be made of ceramic, quartz, or high-temperature alloys. For the previous model, we have produced the tilt angle to ensure that the furnace can be tilted continuously. DC variable speed control and temperature control systems can also be included where needed.

There is a furnace with a wide temperature range. The rotary tube furnace before can be heated to 1,000 degrees Celsius to ensure that it is suitable for all applications.

We are Rotary Tube Furnace Suppliers. We have many years of experience in building rotary tube furnaces and there are many different options. If you need a rotary tube furnace, please contact our team, they can help the whole process, from the initial idea to the aftercare.
