Cement Raw Materials used in Manufacturing of Cement

Raw materials used for manufacturing of Portland cement are found naturally in the earth’s crust. It is made primarily from calcareous and argillaceous materials and gypsum. Calcareous materials contain limestone or chalk while argillaceous materials comprise an oxide of silica-alumina and iron. Both are found as clay or shale.

Raw materials - 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.

The raw materials needed to produce cement (calcium carbonate, silica, alumina and iron ore) are generally extracted from limestone rock, chalk, clayey schist or clay. Suitable reserves can be found in most countries. These raw materials are extracted from the quarry by blasting. They are then crushed and transported to the plant where they are stored and homogenized.

Study of using light-burned dolomite ores as raw material ...

Dolomite can be used as a raw material (α-magnesium oxide) to produce magnesium oxychloride cement (MOC) (Altiner and Yildirim, 2017a, 2017b). Furthermore, owing to the low magnesium oxide content (about 20%) of dolomite, the carbon dioxide (CO 2 ) content released from the dolomite used to prepare MOS cement during the calcination process is about one-third of the amount released from ...

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.

Non-Hydraulic Cement. The non-hydraulic cement doesn't require water to get harden. It gets with the help of carbon dioxide (CO 2) from the air. This type of cement needs dry conditions to harden. Lime, gypsum plasters, and oxychloride are the required raw material to produce non-hydraulic cement. Example: slaked lime is a non-hydraulic cement.

Re: Raw meal to clinker ratio - Page 2 of 5

In a kiln which is being fed with raw meal at 350t/h and has a 'raw meal to clinker ratio' of 1.55 (calculated without respect to bypass), the actual amount of clinker produced with say 10t/h bypass dust removal will be;-(350 / 1.55) - 10 = 215.8t. Therefore the 'raw meal to clinker factor' ,allowing for removal of this bypass dust, will be;-
