    Overall, it is clearly seen that , the cement production involves some complex stages , while concrete production is done by using just cement , water , sand and gravel in concrete mixer .

    The first diagram shows that , limestone and clay are crushed into a powder form, after that, the powder goes into a mixer . Then it passed via rotating heater with the supporting fire in the end of mechanism . After heating step, the powder turns into a paste which is passed to grinder machine to create the cement . Finally , this cement becomes ready to packed in bags.
