Grinding process and particle grading and water demand

At present, the cement grinding of most cement enterprises adopts the double closed circuit combined grinding system of “roller press + ball mill”. The grinding efficiency is indeed high, and the power consumption is indeed reduced. However, due to the excessive concentration of cement particles, the water demand is still high.

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 mill.The raw milling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished cement
