    2.4.1 cement grinding. once the portland cement clinker has been manufactured it is normally fed to a store to effect a measure of blending and also to allow it to cool to ambient temperature. the latter operation is desirable because most of the clinker coolers associated with kiln operation are unable to lower the temperature below 50–80 c, and even at this temperature the amount of heat introduced.

    3. grinding: the clinkers as obtained from the rotary kiln are finely ground in ball mills and tube mills. during grinding, a small quantity, about 3 to 4 per cent, of gypsum is added. the gypsum controls the initial setting time of cement. if gypsum is not added, the cement would set as soon as water is added.
