    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
