Make only Clinker in the state where limestone is available, and then do the grinding of clinker in the region which requires cement. A unit which does both grinding and clinker manufacturing is called an Integrated Unit.

Imported cement and clinker (to make cement) accounted for about 21% of the cement sold; total imports declined significantly, owing to higher domestic production capacity and flattening of overall demand. Clinker, the main intermediate product in cement

Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 °C - 1500 °C. The nodules are ground up to a fine powder to produce cement, with a small amount of gypsum added to control the setting properties.

Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill . The rawmilling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished cement, and has a large effect upon the efficiency of the whole manufacturing process.
