The sinter plant turns iron ore into sinter, which is the optimal product for the blast furnace. Sinter is made by burning a mix of iron ore powder, fluxes and recycled substances from the steel plant to create an opengrained, consistent substance. The sinter is then crushed, cooled and screened for dust. Sometimes, iron ore is supplied in the form of iron ore pellets.

A raw mill is an equipment used to grind raw materials into "raw mix" during the manufacture of cement. Raw mix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement. How Does a Raw Mill Work in a Cement Plant? A raw mill comprises several components that work together to produce the desired raw mix.
