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 ...
Cement production is a highly energy-intensive process. Cement making consists of three major process steps: raw material preparation, clinker making in the kiln, and cement making. Raw material preparation and cement making are the main electricity-consuming processes, whereas the clinker kiln uses nearly all of the fuel in a typical cement plant.
Cement milling is usually carried out using ball mills with two or more separate chambers containing different sizes of grinding media (steel balls). Grinding clinker requires a lot of energy. How easy a particular clinker is to grind ("grindability") is not always easy to predict, but large clusters of belite due to coarse silica in the feed ...
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.

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.

The main task of the cement grinding plant is to grind the cement clinker into particles with a certain fineness to make it into finished product cement. Large cement plants usually include both clinker production lines and cement grinding lines, but there are also independent grinding plants that are only responsible for grinding and ...
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 and grinding is lower than the cost of importing cement, the grinding plants should be profitable for every perceivable shipping cost. The cost difference between the landed cost of cement and the landed cost of clinker consists of three elements. • The FOB price difference of cement and clinker. Currently this is about US$ 5-6

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 ...
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 …
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.
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.
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.

The production process consists of grinding the raw materials to a fine stage, blending them to a uniform composition and heating them to the point of incipient fusion when the cement compounds are formed. The white Portland cement is the product obtained by cooling and grinding the clinker thus formed with gypsum to a fine powder.
