Clinkeris a nodularmaterialproduced in the kilning stage during theproductionofcementand is used as the binder in manycementproducts. The lumps or nodules ofclinkerare 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. ...

Dec 01, 2015· As constituents of theraw materialsand fuels used in theproductionofcement clinker, foreign ions such as Na 2 O, K 2 O, MgO, SO 3, and P 2 O 5 are unavoidably present during the formation of alite. As a result, a limited amount of these oxides are introduced into the chemical structure of alite.

Clinker production. As shown in Fig. 6.6, the feedstock first enters theraw materialto make a fine powder (rawfeed), where 85% of thematerialis slightly smaller than 88 μm.Then, the feed is transferred to the homogenizing silos to impair thematerialdifference. After that, the meal is thrown into the precalciner tower to start the chemical change tocement.

Portlandcement clinker- overview. Portlandcement clinkeris a dark grey nodularmaterialmade 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 producecement, with a small amount of gypsum added to control the setting properties. This page gives a thumbnail sketch.
