This paper looks at the study of intergrinding for the production of ternary cement based on clinker, calcined clay, limestone and gypsum with 50% of clinker substitution (LC 3).The impact of grinding time on clinker, limestone and calcined clay PSD, and how this parameter influences the overall performance of the ternary cement is assessed.

Manufacturing Process – Continental 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.

CEMENT RAW MATERIALS - International Cement Review

Cement clinker is manufactured by heating the blended and ground raw material (typically limestone and clay or shale and other materials) to partial fusion. The clinker burning takes place at a temperature of 1450°C in kilns, which are normally inclined rotating cylinders lined with heat-resistant bricks.
