Alumina Ceramic Roller

High purity Alumina Rollers fulfill different requirements for thermal shock resistance, chemical corrosion resistance, melt and slag corrosion resistance, mechanical stability and gas permeability.


With the state-of -the-art technology and processing, super high temperature ceramic rollers have very advanced features of excellent thermal shock resistance, high bending strength and load capacity. Such this kind of ceramic rollers are used in super wide-body kiln to produce large type polished tiles, glazed tiles such as wall tiles and floor tiles. The maximum working temperature is up to 1350 degree Celsius, and the maximum length is 5200MM.
---High bending strength
---Excellent thermal shock resistance
---No bending and broken.
---Maximum working temperature is up to 1300℃
Such this kind of ceramic rollers are mainly used in the production line of polished tiles, porcelain tiles, rustic tiles, outer all tiles and Glass-ceramics & ceramics combined tile.
