Product Detailed
Related Categories:Ceramics
Detailed Product Description
The picture shows ceramic roller used in roller kilns.
Ceramic Roller is an essential part for various high-temperature roller kilns, it takes the responsibility to drive the product under high temperature. Al2O3 is the main raw material for Ceramic Roller, of course we have to add some other materials to assist Al2O3 to work together to form a high-quality roller. Shaped by special equipment, calcined by elaborately designed furnace and processed by precision, each technical performance is tested strictly, Ceramic Roller is completely conform to roller kiln.
Application:
Glazed tile
Color glazed tile
Porcelain tile
Daily ceramics
Glass ceramics
Electronic ceramics
