Portland Cement Clinker

Clinker is the main component of cement. The production capacity of Sönmez Cement, which produces high quality clinker suitable for all types of cement production in TS EN 197-1 standard and is 2 million tons/year.

The cement production process begins with the extraction of raw materials, mainly limestone and clay. These materials, along with marl and other naturally occurring resources, are extracted from quarries and transported to the production facility. In addition to these primary raw materials, other materials such as iron ore, bauxite, and pumice may also be added to achieve the desired chemical composition for the final product. Portland cement clinker is manufactured from limestone, marl, clay, and iron ore/bauxite as corrector.

The raw materials are initially crushed using crushers to reduce them to smaller sizes. Once crushed, the raw mix is ground in a raw mill and called farin.

Farin is subsequently burned in a rotary kiln at a temperature around 1.450°C. Partial fusion occurs, and nodules of clinker are produced. During the burning process, the raw materials will undergo complex chemical reactions and will eventually leave the kiln as cement clinker. The clinker typically has a composition in the region of 67% CaO, 22% SiO2, 5% Al2O3, 3% Fe2O3, and 3% other components, and normally contains four major phases, called alite, belite, aluminate, and ferrite. Several other phases, such as alkali sulfates and calcium oxide, are normally present in minor amounts. The clinker produced in the kiln is cooled and stored in clinker silos.

The clinker produced by Sönmez Cement is designed for use in the manufacturing of high-quality cement in accordance with the TS EN 197-1 standard. With a production capacity of 2 million tons per year, this clinker is suitable for various types of cement production, ensuring consistency and durability in construction materials. It is intended for use in a wide range of applications, including residential, commercial, and industrial construction projects, where high-performance cement is required.
