As we all know, the cement production can generally be divided into three processes: raw material preparation, clinker production and finished cement production. The cement grinding plant is a vital link of the finished cement production. The cement grinding plant also called cement grinding unit, is used to grind clinker into qualified cement.

This research focused the role to study the effects and ways to control the chemical composition of clinker for better cement production. Cement is a substance produced by grinding a mixture of a clay and limestone and heating to a temperature of 1450°C, in which the chemical transformation occurs inside the kiln to form new compound called clinker.
