However, increasing the SCM level to lower the clinker factor usually results in somewhat poorer cement performance. For example, a 1% increase in SCM can reduce 28-day mortar strength by 0.2 - 0.8MPa, depending on SCM type, cement fineness, grinding system, and clinker characteristics. The impact on strength can be mitigated by increased ...

How Cement Clinker is made? The most common way to manufacture portland cement is through a dry method. The first step is to quarry the principal raw materials, mainly limestone, clay, and other materials. After quarrying the rock is crushed. This involves several stages. The first crushing reduces the rock to a maximum size of about 6 inches.
Cement Production Process. The cement production processes mainly include raw material crushing and storage, raw material proportioning and grinding, clinker calcination, clinker grinding, cement packing, etc. Portland cement is the most widely used cement in our daily life. It is made from a variety of raw materials, typically sand, iron ore ...
White Portland Clinker or white ordinary Portland Clinker is similar to ordinary, gray Portland cement in all aspects except for its high degree of whiteness. Obtaining this color requires substantial modification to the method of manufacture, and because of this, it is somewhat more expensive than the gray product.
With well operated off-white clinker production kiln output can be only a few percent lower than gray clinker production. Clinker grinding and handling: The clinker is next ground to cement (perhaps after a drying stage). Here calcium sulfate is added to control set, in the form of a high-purity grade of gypsum or anhydrite.
Clinker, if stored in dry conditions, can be kept for several months without appreciable loss of quality. Because of this, and because it can easily be handled by ordinary mineral handling equipment, Clinker is also shipped to grinding plants in areas where cement-making raw materials are not available.
It operates a 1.1Mt/yr clinker capacity white cement plant in Mersin and exports its white cement to more than 60 countries around the world. 3. JK Cement (India) is the world's third-largest producer of white cement in 2014 with two white cement plants.
Equation 10: Clinker mass balance For the clinker mass balance at plant level this means: B + S start + C in + K in + P = D + S end + C out + K out + M. where: B = the clinker which is bought from other companies.; S end = the amount of clinker in stock at the end of the reporting year; C in = the amount of clinker in cement which is received from other plants of …
The lower limit for clinker is normally around 0.5% and the upper limit about 2.5%. If clinker is produced with a free lime less than 0.5%, it is likely to be hard to grind and have a low reactivity, resulting in lower cement strengths. If clinker free lime is much higher than 2.5% it is likely to cause unacceptable expansion in the cement, as ...

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.
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.

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.
