Because of the high temperature existing inside a rotary kiln during the clinker manufacturing process, it is necessary to protect the steel shell of the kiln with a refractory lining.
It is not uncommon for the cement rotary kilns all of them operating within a narrow temperature range in the burning zone and having other parameters also similar, yet with large discrepancies as far as their refractory life is concerned. The reason for this can be found in the fact that each kiln has its own specific characteristics and idiosyncrasies which greatly influence its refractory life.
