Clinkerization - Cement Plant Optimization

Higher the AM, lighter the color of clinker (cement). Normal range of SM is 1-2.5. MgO is commonly present in raw meal. Some of the MgO (2%) is accommodated into the clinker mineral structure, while as extra MgO forms a crystal called periclase and causes mortar expansion. MgO up to 4 % is found common in clinker.

Reducing Clinker Content and Carbon Footprint of Concrete ...

Portland cement is the primary binder in Concrete • Portland Cement is manufactured from limestone and shale rocks that have been fired at 1450 C to form a synthetic rock called clinker. This clinker is then crushed to a powder. • When limestone is heated, it gives off CO 2. –CaCO 3 CaO + CO 2 • This reaction is unavoidable in

Energy optimization in cement manufacturing

In the cement manufacturing process large fans draw air through the kiln, precalciner, mills and filters to an ex-haust stack. Many smaller fans push the air into the grate cooler to reduce the temperature of the hot clinker leaving the kiln 1. All these airflows have to be adjusted and controlled as atmospheric conditions, process con-

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.

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. ...

Clinker size and cement grinding GCP Applied Technologies

Clinker size is important for the optimization of cement grinding, and is also an indicator of cement quality. Having a high percentage of coarse clinker can be difficult to grind. However, having a high percentage of fine clinker can also be hard to grind and have a negative impact on cement performance.
