From the quarry to the final product, follow the stages of the cement production process.
Step 1: extraction and preparation of raw materials
The raw materials required for the production of cement are mined from our quarries (limestone, clay, slate, etc.) after geological research and chemical analysis, in specific quantities and proportions.
They are then crushed and transported to the factory to be stored.
Step 2: Grinding raw materials and baking
The ingredients are ground into a very fine powder.
The mixture of materials is homogenized, preheated and then led to the kiln, which is heated by a flame that can reach 2,000°C. The mixture is baked at a temperature of 1,500°C. At this temperature and after chemical reactions, the clinker, the base for the preparation of any kind of cement, is formed.
The clinker is then abruptly cooled by air flow and stored.
Step 3: Grinding cement and distribution
Clinker along with gypsum are ground into a very fine powder, the well-known cement. At this stage various other materials can be added together with gypsum, which are called additives. Using the additives in different proportions we produce specific types of cement.
The cement is stored in silos until it is shipped in bulk or packaged to the customers.
