Cement Kilns: Design features of rotary kilns

Historically, the construction of rotary kiln shells has closely paralleled the construction of boilers. The engineers who pioneered the first rotary kilns all had a background in locomotive construction. Shell sections were made from flat rolled plate, of thickness typically in the range 18-25 mm.

Cement kiln - Wikipedia

The rotary kiln consists of a tube made from steel plate, and lined with firebrick. The tube slopes slightly 1–4 and slowly rotates on its axis at between 30 and 250 revolutions per hour. Rawmix is fed in at the upper end, and the rotation of the kiln causes it gradually to move downhill to the other end of the kiln.
