[0002] Ceramic roller is a kind of high temperature and wear-resistant industrial material, which is often used in the process of transfer, kneading and calendering on the production line. Ceramic roller includes a long cylindrical ceramic roller and a support structure connected to both ends of the ceramic roller. Ceramic roller is generally used to support and transport ceramic tile blanks to be fired in a roller kiln.

[0003] Most of the ceramic rollers on the market are single-layer tubular structures with poor load capacity. Currently, the strength of the rollers is increased by increasing the wall thickness, but the increase in wall thickness leads to an increase in the weight of the roller itself, which in turn weakens its load-bearing capacity and reduces the actual load capacity of the ceramic roller. In addition, the production cost of the roller is increased, resulting in reduced thermal stability and poor heat dissipation capacity of the roller.
