The rotary tube furnace is suitable for the heat treatment of granular or granular materials that continuously flow at high temperatures. It is suitable for materials that need to be treated in air or inert atmospheres and has many applications in research fields such as materials science and geology

Specific applications include: gaseous reduction of ore and analysis of ore and metallurgical slag, synthesis: catalysts; Paint pigments; Burning of Oil Slate: Rare Earth Metal Doping of Ceramics

The working tube or container atmosphere of intermittent and continuous rotary tube furnaces can be: air, inert gas (such as nitrogen or chlorine), and reaction gas (such as hydrogen) (with appropriate safety equipment). Steam injection is also possible.
