  • Cement kiln Wikipedia

    A typical process of manufacture consists of three stages: grinding a mixture of limestone and clay or shale to make a fine "rawmix" (see Rawmill);; heating the rawmix to sintering temperature (up to 1450 °C) in a cement kiln;; grinding the resulting clinker to make cement (see Cement mill).; In the second stage, the rawmix is fed into the kiln and gradually heated by contact with the hot
