Keramull KM RR-LTE

Ceramic roller for roller kiln

Special silicon carbide-based roller for the rapid cooling area of the kiln. The product is characterized by a very low expansion coefficient, remarkable thermal conductivity and an excellent stability in case of high thermal gradient.

Technical specifications

Silicon-carbide based roller, to be used in the cooling zones of the kiln. It is characterized by a high resistance to oxidation and can be used up to 1000°C. It guarantees maximum stability in the event of thermal gradients thanks to its high thermal conductivity and low expansion coefficient.
