Building a cement company

 · Cement is just one ingredient in concrete. A cement plant manufactures a dry powder then supplied to concrete mixing plants. Ready mix is now a genetic term for a concrete plant since nobody manufactures concrete in a "cement mixer" truck now, although you still can if you need to. The model is of a cement plant, not a concrete plant.

Design a new cement plant

Normal practice is to locate the cement plant close to the limestone quarry. This is because 44% of the calcium carbonate, CaCO3, in the limestone will be lost as CO2 in the exhaust gases from the kiln. It is therefore a waste of energy and cost to transport that embodied CO2 a long distance to the cement plant.

 · Cement production begins with limestone, a sedimentary rock. Once quarried, it is mixed with a silica source, such as industrial byproducts slag or fly ash, and gets fired in a kiln at 2,700 degrees Fahrenheit. What comes out of the kiln is called clinker. Cement plants grind clinker down to an extremely fine powder and mix in a few additives.

Cement manufacturing

After cooling, the clinker may be stored temporarily in a clinker store, or it may pass directly to the cement mill. The cement mill grinds the clinker to a fine powder. A small amount of gypsum - a form of calcium sulfate - is normally ground up with the clinker. The gypsum controls the setting properties of the cement when water is added.
