Secondary raw materials (materials in the kiln "raw feed" other than limestone) depend on the purity of the limestone. Some of the second raw materials used are clay, shale, sand, iron ore, bauxite, fly ash, and slag. Coal used to fire the rotary kiln should also be considered a secondary raw material as it contributes its ash to the mix.
