material pre- processing, clinker production, grinding, blending and logistics. Cement grinding stations: Cement production in cement grinding plants is performed by co-grinding clinker and gypsum in dedicated mills (e.g. ball mills, vertical roller mills), and by possibly using further cementitious materials such as slag, fly ash or limestone.

How Clinker Is Made. Seven steps go into the manufacture of clinker – crushing, mixing, grinding, blending, feeding, burning and cooling. The clinker "burning" process is the most vital step. The raw materials of limestone, shale, sandstone and iron ore are coal-fired at a constant temperature of 1,450 degrees Celsius within a 4m wide ...

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 ...

However, by later ages all binders show similar strengths. The results do suggest that for replacement levels up to 15% (mass-basis), intergrinding or blending are both viable strategies to reduce the clinker factors of portland cements, while maintaining early-age properties similar to pure cement formulations.

There are four stages in the manufacture of portland cement: (1) crushing and grinding the raw materials, (2) blending the materials in the correct proportions, (3) burning the prepared mix in a kiln, and (4) grinding the burned product, known as " clinker," together with some 5 percent of gypsum (to control the time of set of the cement).

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 will easily pass through a sieve that is fine enough to hold water.
