ABSTRACT
As a consequence of the chemical reactions and physical operations involved, the cement manufacturing process is a high energy user. The reactions necessary to produce the mineral structure of cement take place at a high temperature in the range 1400 to 1600°C. To ease these reactions, the raw material has to be very finely ground. The cement clinker produced by this pyroprocessing also has to be ground to a very fine state —in order to yield the strength development characteristics needed in a good concrete.
