The first diagram illustrates the process through which
cement
is produced. The process begins when the initial raw materials, namely limestone and clay, are crushed using two rotating drums to make a fine powder which is then
mixed in a cylindrical mixer. The next stage involves a tube-like rotating heater with a blowtorch mounted at its bottom opening. The mixed powder is fed from the top and simultaneously heated and blended, after which it is transferred to a grinder using a conveyor belt. There, it is milled to yield the final cement
product which is eventually packed in bags.
This
cement
is used as raw material in the production of concrete in a second,
rather simpler process illustrated in the second picture. An initial mixture comprising 15% cement
, 10% water, one-quarter sand and half gravel is fed into a rotating concrete mixer where they are stirred until the concrete mix is ready for construction purposes.
To sum up
, there are 5 stages in the production of cement
. Moreover
, cement
and a few other simple ingredients are used to produce concrete through a single-stage procedure.Submitted by Amir Rustamov on
