Portland Cement Plants Cement Clinker Production Portland
Ceramic wastes as alternative raw materials for Portland cement clinker
Portland cement clinker production consumes large amounts of energy (850 kcal per kg of clinker) and has a considerable environmental impact.This involves massive quarrying for raw materials (limestone, clay, etc.), as it takes 1.7 tonnes to produce 1 tonne of clinker, as well as the emission of greenhouse and other gases (NO x, SO 2, CO 2) into the atmosphere.

How Cement is Made
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.
