Portland cement clinker

Portland cement clinker - overview. Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 °C - 1500 °C. The nodules are ground up to a fine powder to produce cement, with a small amount of gypsum added to control the setting properties. This page gives a thumbnail sketch.


CLINKER GRINDING IN CEMENT PRODUCTION

Feb 21, 2019· The base minerals contained in clinker: Alite (C 3 S = 3CaO*SiO 2 ) is a soft material, Mohs hardness is 3.2–3.4, the mineral is very fragile and easily damaged. Belite (C 2 S = 2CaO*SiO 2 ) is the second major mineral of Portland cement clinker, it characterized by a slow hardening, but provides achieving high strength during long ...


Cement mill - Wikipedia

The hardness of clinker is important for the energy cost of the grinding process. It depends both on the clinker's mineral composition and its thermal history. The easiest-ground clinker mineral is alite, so high-alite clinkers reduce grinding costs, although they are more expensive to make in the kiln.

PAPER OPEN ACCESS …

Comparison between grinding of cement clinker with and without grinding aid (after Fuerstenau, 1990) Figure 1 shows the typical comparison between grinding of cement clinker with and without a grinding aid in a laboratory mill. As discussed in the literature [1,2,4], there was significant effect of using grinding aid in cement grinding.


Efficiency of grinding stabilizers in cement clinker ...

Apr 01, 2013· The diameter of the grinding chamber D = 200 mm was the same as its length L. The mill chamber was constructed of porcelain and the grinding body stock consisted of 133 corundum balls of 25.1 mm diameter and 11,500 steel beads of 4.9 mm diameter.The grinding stock formulation arose as a result of many years development of ultra-fine cement clinker milling processes.


INVESTIGATION ABOUT THE EFFECT OF CHEMICAL …

Cement manufacturing involves a grinding process of clinker, gypsum and secondary mineral additions, usually carried out in ball or vertical roller mills. Efficiency of grinding (in terms of energy actually used to increase cement fineness over total energy) is …


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.


The influence of grinding mechanism on the liberation ...

Mar 01, 2006· The emphasis was given to the preferential liberation of the constituent clinker phases. High-pressure grinding rolls gave higher degrees of liberation of mineral phases arising from the intergranular breakage along the grain boundaries compared to ball mill grinding. This is expected to influence the downstream service properties of cement.


Resistance to Grinding and Cement Paste Performance of ...

Apr 19, 2021· Apr 19, 2021· Mineral processing requires processing heterogeneous mixtures of ores. For instance, the finished cement is manufactured by grinding clinker and small amounts of gypsum to control cement´s setting upon hydration .


The influence of grinding technique on the liberation of ...

Sep 01, 2007· The greatest interest in this study was obviously to determine if there were any differences between grinding mechanisms in terms of mineral liberation; and their influences on main cement service properties. Clinker minerals, mostly C 3 S and C 2 S can be seen together within liquid phase, expressing a locked type of mineral. It is known that ...

When raw materials availability, funding, schedule or other factors do not support the implementation of a full clinker/cement manufacturing facility at a location, a Satellite Cement Grinding Plant could be a strategic alternative solution. Additives used in blended cements, such as pozzolan or slag, may not be available at the location of the clinker plant. […]
