which chemical spray on cement clinker

cement chemistry arthurharrisson

The clinker chemistry model as commonly used starts with the premise that the essential ingredients of cement clinker are the four oxides; SiO 2, Al 2 O 3, Fe 2 O 3 and CaO which, when heated to approximately 1450C in the cement kiln, form the four compounds; Ca 3 SiO 5, Ca 2 SiO 4, Ca 3 Al 2 O 6 and Ca 2 AlFeO 5.

Higher the AM, lighter the colour 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.

Cement Cargo Handbook the world's largest cargo

Cement clinker is the semi-manufactured material, usually very hard grey granules between 1 and 20 mm in diameter. It is substantially unaffected by water but should be kept dry to avoid caking. Contamination with sea water will increase the chloride content of the clinker and the cement produced from it.

Effect of chemical composition of clinker on grinding

About 30% of the energy required to produce one ton of cement is consumed in grinding. It is a significant percentage of the total cost of cement. The energy consumption in the cement mills varies between 16.5 to 63.5 kWh/ton with an average of 36kWh/ton . There are numerous factors affecting the energy consumption during clinker grinding.

Manufacture of Portland cement

The raw materials used in the manufacture of Portland cement consist mainly of lime, silica, alumina and iron oxide. These compounds interact with one another in the kiln to form a series of more complex products and, apart from a small residue of uncombined lime which has not had sufficient time to react, a state of chemical equilibrium is reached.

Jul 14, 2017The C 3 A in portland cement clinker, which typically contains about 13% oxide substitution, is primarily cubic, with smaller amounts of orthorhombic C 3 A. The C 3 A and C 4 AF minerals form by simultaneous precipitation as the liquid phase formed during the clinkering process cools, and thus they are closely intermixed.
