    Boulder formation mechanism: Large clinker balls initiate and grow behind a thick coating or ring. Build up often fall and slide into the kiln as large slabs and coming to rest behind a ring (if it is large enough). The slab can roll around behind the ring forming a ball which can then grow larger due to accretion.

    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.
