I am also telling you that a wellgraded cement also improves the strength of concrete. the fig.1. show the flow diagram of the dry process of the manufacture of cement. 1. dry process. in the dry and semidry process the raw materials are crushed in a dry state. then, they are processed in grinding mill, dried and reduced to very fine powder.
In this process, the raw materials are first reduce in size of about 25 mm in crushers. a current of dry air is then pass over these dry materials. these dry materials are then pulverise into fine powder ball mills and tube mills. all these operations are do separately for each raw material and they are store in hoppers.
There is a horizontal filled with steel balls. clinker reach in this rotating drum after cooling. here, steel balls tumble and crush the clinker into a very fine powder. this fine powder is considered as cement. during grinding gypsum is also added to the mix.

What Is The Manufacturing Process Of Portland Cement
It is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker, grinding the clinker, and adding 23 percent of gypsum. several types of portland cement are available. the most common, called ordinary portland cement (opc), is grey, but white portland cement is also available.
The major raw materials of portland cement making are limestone, clay, and sand which cover calcium, silicon, iron, and aluminum. limestone is mainly for calcium. it is combined with smaller proportions of sand and clay. sand & clay fulfill the need for silicon, iron, and aluminum.
