CEMENT RAW MATERIALS

The quality of cement clinker is directly related to the chemistry of the raw materials used. Around 80–90% of raw material for the kiln feed is limestone. Clayey raw material accounts for between 10–15%, although the precise amounts will vary. Magnesium carbonate, which may be present in limestone, is the main undesirable impurity. The level

RAW MATERIALS IN CEMENT PRODUCTION

The main materials used in cement production are minerals containing calcium oxide, silex, alumina and iron oxide. These components are rarely found in one type of raw material; therefore, for the cement production the raw mix is selected for the following components: CARBONATE COMPONENT (rich in calx) is contained in the raw mix in a quantity of 76-80%: Limestone. Mohs hardness is 1.8-3.0 ...

Raw materials - Understanding Cement

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. Supplementary materials are used to adjust the composition of ...

What is Cement Clinker? Composition, Types Uses - Civil ...

Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln. ...

Cement Clinker Production - an overview ScienceDirect

Used in the plant, limestone (55–60%), marl (35–40%), and copper slag (2.5–6%) are used as cement raw materials for the production of clinker. The clinker is then finely ground in a ball mill grinding circuit together with a small amount (typically 4%) of gypsum to produce cement in the Turkey Trabzon Cement Plant ( Alp, Deveci, Süngün, 2008 ).

Cement clinker - Wikipedia

Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.

About Cement – Cement

The process begins with the mined raw materials being ground into a raw meal ready for the kiln. This precise mixture of ground limestone, clay and sand is heated in the precalciner before being fed into the kiln where it is transformed (calcined) into clinker at very high temperatures – typically around 1,450˚C.

Clinker Production Clinker Plant Cement Plant

After the raw material is preheated and precalcined, the next step is clinker manufacturing. In the rotary kiln, the carbonate is further rapidly precalcined and a series of solid phase reactions occur to form minerals in the cement clinker. As the temperature of the material increases, the mineral becomes a liquid phase and reacts to form a large amount (clinker). After the clinker is fired ...
