The basic layout of a cement plant has been as above since the early nineteenth century. Two raw materials-one high in calcium and one low in calcium-are crushed, then finely ground together in a rawmill to make " rawmix ". The rawmix is burned in a kiln with fuel to make clinker. The clinker is finely ground with a small addition of gypsum
