ROTARY KILN CHAIN SYSTEMS At the cold end of the kiln, the relatively low gas temperature hampers heat transfer. To improve this, a section of chain is hung from the shell in this part of the kiln. This chain is made up of links that are typically ¾ in. by 3 in. (1.9 cm x 7.6 cm). Hangers attach lengths of this chain directly to the kiln shell
