Limestone is the most important raw material in the manufacture of cement as it provides the main ingredient CaO. It is blended with other raw materials such as clay, marl, shale and corrective additives to prepare a mix with the four main ingredients, CaO, SiO2, Al2O3 and Fe2O3 in the correct proportion.
The Main Types and Application of Raw Material Mill: Raw material mill products are mainly used for grinding of cement raw materials, also applies to the metallurgical, chemical, electric power and other industrial and mining enterprises for grinding all kinds of ore and other grindable material.
Fuels and Raw Materials A range of nontraditional or alternative materials can be used in cement production where such materials retain a calorific value (replacing traditional fossil fuels), or where there is a material substitution value (replacing natural raw materials).

materials The main raw materials used in cement manufacture are limestone, shale, clay, sand and iron ore. These natural materials are extracted from mines and transported to the cement plant, where they are blended to manufacture the required cement quality.
High quality cement due to the use of natural high quality raw materials obtained locally. Advanced technology used by manufacturers offers higher volume production in less time. Competitive price and availability of large volumes due to high number of manufacturers.
SOLIDIA CEMENT ™. The process leverages the same raw materials, equipment and manufacturing processes that are used by the cement industry today. OPC is manufactured on massive scales, in large rotary kilns, burning inexpensive, ubiquitous raw materials such as limestone, clay and sand. Over 108 tons per year of OPC is made in 100 plants...
Proportioning of the raw materials is based on a series of simultaneous calculations that take into consideration the chemical composition of the raw materials and the type of cement to be produced: American Society for Testing and Materials (ASTM) Type I, II, III, or V white cement, or American Petroleum Institute (API) Class A, C, G, or H.
