Step 6 : Finish Grinding. The clinker is ground in a ball mill—a horizontal steel tube filled with steel balls. As the tube rotates, the steel balls tumble and crush the clinker into a super-fine powder. It can now be considered Portland cement. The cement is so fine it …
and alumina. Finished cement is produced by finely grinding together around 95% cement clinker with 5% gypsum (or anhydrite) which helps to retard the setting time of the cement. The quality of cement clinker is directly related to the chemistry of the raw materials used. Around 80–90% of raw material for the kiln feed is limestone.
Blended Cement. Blended cements are produced by inter-grinding Portland cement clinker (Clinker is the main product of Portland cement manufacture and is generated by heating raw materials (limestone, iron ore, and alumino-silicates such as clay) together at temperatures of about 1400–1500°C.) with supplementary cementitious materials (SCMs) or by blending Portland cement with SCMs such as ...
