Limestone is not available at the cement manufacturing location.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.,

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. Clinker grinding with limestone - Page 1 of 1,Dec 08, 2014· re Clinker grinding with limestone. Hello Shastri, 100oC seems a bit low. Normally you should try to keep the mill outlet temperature at between 110 and 115oC. Have you tested the water content of the cement blocking the diaphragm? If you use water sprays they may not be atomising correctly, causing localised buildup of moist cement.Manufacturing Process of Portland Cement - TCL Blog,Aug 26, 2014· Clinker, along with gypsum, is sent to the Grinding Ball Mill, for final grinding. In addition to Gypsum, Fly ash, pozzolan, limestone and slag may also be added to the cement in final grinding. This produces new compounds which lead to special characteristics. As such the cement can then be classified as Blended Cement.
