摘要：PROBLEM TO BE SOLVED: To provide an external heating rotary kiln in which a ceramic core tube is protected against cracking while ensuring a high thermal efficiency. SOLUTION: A ceramic core tube 1 is covered with a metallic protective tube 2 and supported softly, at the parts covering the opposite ends of the core tube 1, by a ground packing 4 used as a shaft sealing member at the rotary part. Since the core tube 1 is not required to be tightened at the supporting part and can slide in the axial direction of the core tube 1, undue thermal stress or thermal stress gradient is not generated in the axial and circumferential directions of the core tube 1. Consequently, the ceramic core tube 1 is protected against cracking and a high thermal efficiency can be ensured.
