Portland cement clinker
Cement is a mixture of Clinker, Gypsum and Filler (Limestone). Clinker constitutes 80% of the cement whereas Gypsum 5% and Limestone (or other constituents) 15%. Clinker and Gypsum are imported from the international market. (Illustration 1) The raise of raw material prices during the last 12 months has been a big challenge for the cement industry.

Portland cement clinker is made by heating a homogeneous mixture of raw materials in a rotary kiln under high temperatures. The main raw material for making and producing cement clinker is mainly limestone, which is combined with another raw material containing clay as a source of aluminum silicate.

Sulphates may be present in clinker up to about 3%. Sulphur in raw materials increases SOx emission and cause build-up in preheater. Sulphate can form a stable compound with Potassium (K2SO4) and to lesser extent Sodium (Na2SO4). The sulphates in the clinker comes from raw materials and fuel.

By Darrell Leetham 01.14.2014. Clinker quality depends on raw material composition. Portland cement is the most common type of cement in the world. It is used primarily to make concrete, mortar, and grout. Portland cement manufacturing begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called

Technically, a cement producer can have almost complete control over clinker composition by blending raw materials of different compositions to produce the desired result. In practice, however, clinker composition is largely determined by the compositions of the locally-available raw materials which make up the bulk of the raw meal.
