The Cement Manufacturing Process Advancing

· Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay to a fine powder called raw meal which is then heated to a sintering temperature as high as 1450 °C in a cement kiln In this process the chemical bonds of the raw materials are broken down and then they are recombined into new compounds The result is called

Rawmill Wikipedia

A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement Rawmix is then fed to a cement kiln which transforms it into clinker which is then ground to make cement in the cement raw milling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished cement

Gypsum Addition an overview ScienceDirect

Cement milling comprises two stages crushing the large clinker grains down to a powder then grinding the powder to the size required In some instances these processes are separated to the extent that the crushing stage is accomplished in a roller press and the grinding in a small finish mill In most cases however the two are combined within a single mill either as two chambers separated
