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 precalciner kiln system. The durability of the rotary kiln brick lining generally determines the duration of a kiln operating campaign.
