There are many refractory materials that can be used to form the refractory lining of cement rotary kilns.The refractory lining on the interior of the cement rotary kiln is a crucial component in ensuring the kilns working efficiency and protecting the kiln shell from melting down.. There are many refractory materials that can be used to form the refractory lining of cement rotary kilns.Refractory is a critical component in maintaining process efficiency, as well as prolonging the life of the Kiln. The durability of the rotary kiln brick lining generally determines the duration of the kiln operating campaign. Refractory protects the shell of the kiln from the temperature within, and also helps toRequirements for Refractory Materials of Cement Rotary Kilns. The sintering zone has the worst working environment in the whole cement rotary kiln system. It bears more abrasion than the preheating zone and cooling zone. Its service life mainly depends on the durability of the lining refractory materials at the sintering zone.
