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.
