Stage of Cement Manufacture. There are six main stages of the cement manufacturing process. Stage 1: Raw Material Extraction/Quarry The raw cement ingredients needed for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale, and bauxite. The ore rocks are quarried and crushed into smaller pieces of about 6 inches.

The clinker cooling process is a crucial step in cement manufacturing, ensuring the quality and efficiency of production. Modern grate coolers are used to rapidly cool the clinker from 1400°C to around 100°C. This rapid cooling not only solidifies the clinker but also facilitates proper crystal formation, which is essential for maintaining high clinker quality.
