Characterization of raw materials and final product in the cement manufacturing

raw materials of silicate character and corrective raw materials with high content of iron oxide The basic raw materials for cement production are limestone and clay The limestone represents the dominant component most often 75 clay and corrective raw materials remaining 25 of the raw Raw material proportioning The homogenized limestone and clay/silcastone along with other raw materials like sand and iron ore are reclaimed into separate feed bins The proportional ratio of the raw materials is fixed using raw mix design and is determined from the chemical analysis of the raw materials
