Aug 30, 2012 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 amp clay fulfill the need of silicon, iron and aluminum.
Cement is the main basic ingredient of ready-mix concrete. Whether in bags or in bulk, CEMEX provides its customers with high-quality branded cement products for their construction needs. Cement is a fine powder, obtained from the calcination at 1,450 C of a mix of limestone, clay, and iron ore.
Cement is typically made from limestone and clay or shale. These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. This blended raw material is called the raw feed or kiln feed and is heated in a rotary kiln where it reaches a temperature of about 1400 C to 1500 C.
