Clinker is anodularmaterial 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.

The process that cement raw materials is sintered in a kiln is the key to the quality of cement clinker. In the sintering process of cement raw material, the useful components decomposed by various raw materials at 1000 °C are mainly:calcium oxide (CaO),silicon dioxide (SiO 2),aluminum oxide (Al 2 O 3), andferric oxide (Fe 2 O 3). And the solid-state reaction occurs to a small amount of oxide at about …

Get PriceTechnically, acementproducer can have almost complete control overclinker compositionbyblending 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.
Get PriceThe resulting clinker (rounded nodules between 1mm and 25mm across) is ground to a fine powder in a cement mill and mixed with gypsum to create cement. The powdered cement is then mixed with water and aggregates to form concrete that is used in construction. Clinker quality depends on …
Get PriceThe cement clinker in these studies contained a small amount of CS, ranging from 0.3% to 2.5%, and possibly in combination with other waste materials such as ashes from sewage sludge, municipal incineration and coal combustion, sewage dry powder and aluminium dross that together amounted to around 8–40% of the total raw feed composition, as provided in Table 8.2.
Get PriceIn the clinker burning process, in order to produce 1 tonne of clinkers, 1.52 tonnes of raw materials are used on average. The balance of 0.52 tonne of raw materials is converted mainly to carbon dioxide by the processes such as CaCO 3 → CaO + CO 2. This is a serious global environmental problem since increase in carbon dioxide in the atmosphere has direct consequences on global warming.

Get PriceThis produces clinker, the basic material required for the production of all cements. Clinker is the main ingredient in cement. These hardened granules are obtained by firing a mixture of approximately 80% limestone and 20% clay to a high temperature. Cement is obtained by grinding clinker, in some cases supplementing it with additives.

Get PriceIn 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 the raw meal but cost and availability are likely to determine the extent to which they are used. Transport costs in particular become significant in view of the large quantities of …
Get PriceCement is produced by grinding clinker (added with different active ingredients to achieve the desired properties of cement) into a fine powder. 4 The composition of a typical good quality clinker for general use: 37-72% of 3CaO.SiO 2 ; 6-47% 2CaO.SiO 2 ; 2-20% 2CaO.Al 2 O 3 ; 2-19% 4CaO.
Get PriceThe cement production process begins with the extraction of limestone and clay from the quarry. The material is then blended, crushed and fed to the kiln. Post-kiln, the clinker is cooled and goes through a final grinding method before it is ready to ship.
Get PriceThe cooled clinker is a kind of granular material with different particle size. They will be ground in the grinding mill to reach the qualified fineness of cement product. During the grinding, 2-3% gypsum powder is added as retarder so that when cement contacts with water, its solidification speed will not be too fast.
Get PriceOrdinary Portland Cement Clinker is the core component in producing cement which is formed by sintering limestone. In the manufacturing of Portland cement, clinker formed by sintering or fusing together without melting to the point of liquefaction, alumina-silicate materials such as clay and limestone during the cement kiln stage and happens as 3 millimeters (0.12 in) to 25 millimeters (0.98 …
