The effects of grinding on the properties of Portland

It is shown that the grinding quality greatly controls the properties of Portland-limestone cement. • It is especially the fineness of Portland clinker that is important because the limestone (more soft) is always finer. • Crushed limestone (fillers) behaves like crushed Portland clinker for the powder packing density and the pastes

Manufacture of Portland cement

grinding mill, where they are dried and reduced in size to a fine powder. The dry powder, called raw meal, is then pumped to a blending silo, and final adjustment is now made in the proportions of the materials required for the manufacture of cement. To obtain a uniform mixture, the raw meal is blended in the silo, usually by means of compressed air.

How Portland Cement is Made? Manufacturing Process of

The clinker is then ground to produce portland cement. Gypsum is added during the grinding process to control the set rate of the cement. Slag and fly ash can also be added to control other properties of the final product. Both the dry and wet processes are very energy intensive.

Coal in the cement industry

The cement clinker is ground with about 5% gypsum. Other materials like slag, fly ash, ash of coal etc may also be added in required proportion to get the final cement powder. The main fuel used for firing preheater cyclone and rotary kiln is coal. Therefore, coal plays an important role in the manufacturing process of cement. Based on the
