Cement Industry | Cement Rotary Kiln | Refractory Lining ...

Refractory life is directly proportional to the number of shutdowns for a cement rotary kiln. The more shutdowns, the shorter is the refractory life (what is Spalling Resistance of the Refractory).The danger of damaging the refractory is directly related to the rate of cooling down of the kiln, the danger being the greatest when cooling is too rapid.

US4973245A - Method for cooling a kiln furnace - Google ...

The invention relates to a method for cooling a rotary kiln furnace with a liquid cooling agent. The shell of rotary kiln is usually cooled off with air by intermediation of free convection, or by means of forced convection. The bricklining in these furnaces tends to wear, so that it has to be replaced once or twice a year.
