The Cement Production Process The McIlvaine Company

The Cement Production Process. Another process, the semi-dry process, is used where there is a requirement for the raw materials to be in the form of nodules or pellets. For example, the Lepol kiln requires water to be added to the raw mix to form pellets that can be preheated by the hot kiln exhaust gases on a grate preheater.
