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 …

The strength indication for cement has only a limited effect on the strength of concrete or mortars to be achieved. This is because a type of concrete with among others a lower water-cement factor (the ratio of cement as opposed to water) than the type of mortar can be created, which is used for the strength classification of cement.
effect of clinker temp in cement grinding sale. May 01 1982 · The temperature at which Portland clinker and gypsum are ground together to produce Portland cement is shown to influence the subsequent early hydration behaviour Raising the grinding temperature from 90°C to 130°C and thence to 170°C has resulted in increased ettringite being present at all the …
There are many factors that affect the quality of cement, such as the strength of clinker, the specific surface area of cement, particle size distribution, cylindricity, mixing amount of mixed material, etc., the influence of cement water is also crucial, cement water must be strictly controlled within a certain reasonable range.
With the growth of Fe2O3 grindability increases. With the growth of clinker density grindability increases. The higher raw mixture density, the worse grindability. The higher C3S (alite), the better grindability. The higher C2S (belite), the worse grindability. The more liquid phase, the worse grindability.
