Roller Hearth Kiln (Calcination)

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
