2.A.1 Cement production GB2009
Cement manufacture is a major mineral commodity industry. During the manufacturing process natural raw materials are finely ground and then transformed into cement clinker in a kiln system at high temperatures. The clinkers are cooled and ground together with additions into a fine powder known as cement.

How Cement Is Made
Clinker is discharged red-hot from the lower end of the kiln and generally is brought down to handling temperature in various types of coolers. The heated air from the coolers is returned to the kilns, a process that saves fuel and increases burning efficiency. After the clinker is cooled, cement plants grind it and mix it with small amounts of

Cement Types
In the most general sense, portland cement is produced by heating sources of lime, iron, silica, and alumina to clinkering temperature (2,500 to 2,800 degrees Fahrenheit) in a rotating kiln, then grinding the clinker to a fine powder. The heating that occurs in the kiln transforms the raw materials into new chemical compounds.

What Is Cement
Bottle kilns ate the traditional types of kilns followed by chamber kilns and then continuous shaft kilns were invented. The shaft kiln is used in many countries in modern days but the dominant means of burning is the rotary kiln.

Cement Clinker Substitution. Cement clinker substitution occurs when clinker, the primary material used in cement manufacturing, is substituted with other cementitious materials, such as coal fly ash or blast furnace slag.
