clinker required to produce cement

Manufacturing process | Home : Lafarge Cement

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. Suitable reserves can be found in most countries. These raw materials are extracted from the quarry by blasting. They are then crushed and transported to the plant where they are stored and homogenized.

Raw materials Understanding Cement

Technically, a cement producer can have almost complete control over clinker composition by blending raw materials of different compositions to produce the desired result. In practice, however, clinker composition is largely determined by the compositions of the locallyavailable raw materials which make up the bulk of the raw meal.

Cement Kilns: Clinker

Clinker minerals react with water to produce the hydrates that are responsible for cement’s setting and strengthgiving properties. Reaction with water occurs only at the surface of the clinker particle, and so only proceeds rapidly if the clinker is finely ground to produce a large reaction surface.
