Tunnel kiln

Our tunnel kilns are constructed completely with refractory materials. The clay analysis give us the data in order to utilize the right percentage of alumina to any different firing temperatures.
The first part, namely the preheating zone, is used an anti-acid refractory material. While the cooking zone is made with an alumina content from 42% up to 60%. The cooling zone is built using 25% of alumina.
The insulation, our strong point, is entirely mounted on dry way. It is calculated and created a package using: calcium silicate for high temperatures, kaolin wool and rock wool.
The quality of the material used, makes our tunnel kiln very flexible and, most important, it significantly lowers the energy consumption of Kcal destined for firing.
