Cement Manufacturing Process

Stage of Cement Manufacture. There are six main stages of 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 to smaller pieces of about 6 inches.

Manufacturing process Home : Lafarge

From the limestone quarry to the delivery of the end product, follow every step in the cement manufacturing process. Step 1: extraction of raw materials The raw materials needed to produce cement calcium carbonate, silica, alumina and iron ore are generally extracted from limestone rock, chalk, clayey schist or clay.

Cement Manufacturing Process Phases Flow Chart

Cement Manufacturing Process Phase 1: Raw Material Extraction. Cement uses raw materials that cover calcium, silicon, iron and aluminum. Such raw materials are limestone, clay and sand. Limestone is for calcium. It is combined with much smaller proportions of sand and clay. Sand and clay fulfill the need of silicon, iron and aluminum.

Cement

Cement - Cement - Extraction and processing: Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.
