design of a rotary kiln for cement production

Cement Kilns: Design features of rotary kilns

The bricks for cement kilns have to be made in a special tapered form in order to fit the curvature of the kiln shell. The iron and steel industries had prompted the production of refractories with a wide range of sophisticated chemistries, but it took some time for rotary cement production to increase to the stage at which these ideas were applied to cement kiln bricks.
