PRODUCTION OF PORTLAND CEMENT Production of Portland cement is a complex technological process that consists of two basic steps. In the first, through heat processing entering raw materials are fundamentally altered creating cement clinker. In the second, by grinding and milling clinker wit gypsum the final product – cement – is manufactured.

Gypsum which controls the settling of cement. The calcareous and argillaceous raw materials are dried, mixed and heated to a high temperature (around 1000 0 C) in a furnace. The produced granular form is called clinker. Then it is ground with 4% gypsum to obtain Portland cement. There are two main processes in manufacturing Portland cement.
