  • Rotary kiln - Wikipedia

    The rotary kiln was invented in 1873 by Frederick Ransome. Kiln shell. This is made from rolled mild steel plate, usually between 15 and 30 mm thick, welded to form a cylinder which may be up to 230 m in length and up to 6 m in diameter. Upper limits on diameter are set by the tendency of the shell to deform under its own weight to an oval cross section, with consequent flexure during rotation ...
