Abstract: PURPOSE:To perform a heat treatment for accelerating a solid phase reaction in a uniform and energy saving manner by providing an inclined double pipe comprising an independently rotatable outer pipe and an inner pipe and providing a heater on the outer periphery of the outer pipe. CONSTITUTION:An annular treatment space 4 is formed between an independently rotatable outer pipe 3a and an inner pipe 3b of an inclined double pipe 3 and ceramics raw material is fed into said space 4 from a raw material feeder 5. On the opposite side of the feeder 5 a closing device 6 is provided to discharge burnt items and heaters 7 are provided on the outer periphery of the outer pipe 3a. The pipes 3a, 3b are rotationally driven by a driver 8 and the ceramics raw material fed from the feeder 5 is transferred through the space 4 by the rotation of the pipes 3a, 3b, while it is burnt under the temperature control of heaters 7. As a result, dispersion in quality due to deflection of flow of the material can be avoided and rough crushing can be effected simultaneously with calcination.
