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.
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. .

Optimization of Cement Sulfate Part I - Cement without admixture Introduction In 1946 William Lerch published a paper on the optimum sulfate content in Portland cement, which demonstrated that the optimum sul-fate content with respect to mortar strength correlated closely with heat of hydration measured by isother-mal calorimetry, and also with the
• 6. Clinker is cooled to a temperature of about 60-150oC and stockpiled. • 7. Clinker is ground to the specified fineness with the addition of a small proportion of gypsum to control the setting time of the finished cement. • 8. The finished cement is stored in silos for a relatively short time before
Clinker rapidly burned at the minimum temperature for combination, then rapidly cooled, contains small, defective crystals that grind easily. These crystals are usually also optimal for reactivity. On the other hand, long burning at excess temperature, and slow cooling, lead to large, well-formed crystals that are hard to grind and un-reactive.
Clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement. The powdered cement is then mixed with water and aggregates to form concrete that is used in construction. The composition of clinker, such as free lime, has to be closely monitored to ensure the quality of the cement.
