Definitions

  • the thermal conditioning method of the present invention Due to the use of the thermal conditioning method of the present invention, the very long and time-consuming drying of wet ceramic materials or articles in a conventional drier is reduced drastically.
  • the internally heated conditioned articles can enter directly into a high temperature drying region at up to 100°C without the danger of any thermal gradients or sudden drying cracking the material.
  • the present method can be implemented on wet ceramic materials or products that either move continuously between the shaping process to the dryer or remain in a chamber.
  • the present method can be implemented in-series with the existing production line without any changes, or at least with minor changes to the existing equipment in any ceramic factory. For example, in a brick factory, drying of wet bricks can take up to 48 hours in a traditional drier.
