Roller Hearth Kiln Solutions for Battery Material Calcination

What is Roller Hearth Kiln (RHK)?

Roller Hearth Kiln (RHK) is a continuous firing furnace which transports products using ceramic rollers.
RHK provides outstanding temperature uniformity, cleanliness and heat efficiency.

₋ Uniform Temperature Distribution: RHK’s roller transportation method makes radiant heating from all direction possible.

- Clean Atmosphere: RHK materials are composed of ceramics which helps maintain a clean atmosphere.

- Energy Saving and Space Saving: The combination of uniform heating and high speed firing allow for high efficiency production with energy and space savings.
