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).
