Grinding In Portland Cement Production

Type 1. Portland Pozzolana Cement (IS 1484 1991) An inter ground or blended mixture of Portland cement and pozzolana is called Portland pozzolana cement. This cement can be manufactured either by intimately inter grinding Portland cement clinker and Pozzolana or by intimately and uniformly blending Portland cement and fine Pozzolana.

    A ball mill is a rotating drum filled with steel balls of different sizes (depending on the desired fineness of the cement) that crush and grind the clinker. Gypsum is added during the grinding process to provide means for controlling the setting of the cement. The cement is bagged transported for concrete production.After the clinker is cooled, cement plants grind it and mix it with small amounts of gypsum and limestone. Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready mix concrete companies to be used in a variety of construction projects.

    In practice, portland limestone cement is ground to a higher fineness compared to portland cement. An increase of Blaine in the range of 100cm 2 g is necessary to compensate for the strength reduction resulting from the addition of 1 limestone. 3. The mill type and process system play an important role.Portland cement is the most widely produced cement, both in the UK and worldwide. The blended cements are produced by finely grinding Portland cement clinker with energy efficient dry process. In Europe, for example, about 78 of cement production is from dry process kilns, a further 16 of production is accounted for by semi dry semi wet.
