Cement Kilns Design features of rotary kilns
A typical long-term-mean refractory consumption of a wet process kiln would be in the range 1-2 kg per tonne of clinker made so the refractory was still a significant running cost. With the advent of more efficient dry processes and particularly precalciners the relative cost of refractories has been reduced mainly because of the larger

Cement kiln refractoriesUnderstanding Cement
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 operating campaign.
