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.
Kiln plants with two and three station rotary kilns from KHD Humboldt Wedag are top of the line. One reason: highly efficient precalcining systems, which were developed by KHD Humboldt Wedag, revolutionizing the clinkering process. Rotary kilns no longer have to function as calciners which mean that they can be substantially smaller in size.

Manufacturing - the cement kiln. Most Portland cement is made in a rotary kiln. Basically, this is a long cylinder rotating about its axis once every minute or two. The axis is inclined at a slight angle, the end with the burner being lower.
Cement kiln refractories. Refractories play a critical, if unseen, role in both the rotary kiln lining, and the lining of the high volume static equipment areas that comprise a modern pre-calciner kiln system. The durability of the rotary kiln brick lining generally determines the duration of a kiln …
Rotary kilns work by processing material in a rotating drum at high temperatures for a specified retention time to cause a physical change or chemical reaction in the material being processed. The kiln is set at a slight slope to assist in moving material through the drum.
