The raw materials used for the preparation of the raw meals were limestone, shale, lava, ILS and WFA. Limestone and shale are quarried raw materials which are typical in cement production due to their oxide content in CaO, SiO 2, Al 2 O 3 and Fe 2 O 3. Lava is the solidified form of the magmatic material (Τ = °C).

A cement mill is a fundamental component of the cement manufacturing process, playing a vital role in breaking down and grinding cement clinker into fine powder. This finely ground powder, when mixed with other materials, produces the building material we commonly know as cement. To achieve this crucial transformation, a cement mill comprises several intricate parts, each serving a distinct ...

Cement raw materials (limestone, chalk, and clay) are selected and crushed. Classifiers are used to separate the fine particles from the coarse ones. Grinding is then used to further reduce the size of the raw materials. The resulting material is then proportioned so that is has the proper chemical composition and fineness and is then homogenized.
