  • The Cement Kiln Understanding Cement

    The original rotary cement kilns were called 39wet process39 kilns. In their basic form they were relatively simple compared with modern developments. The raw meal was supplied at ambient temperature in the form of a slurry. A wet process kiln may be up to 200m long and 6m in diameter. It has to be long because a lot of water has to be evaporated
