PROCESS CONTROL FOR CEMENT GRINDING IN
The power ingesting of a grinding process is 50-60% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 30-40% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and Grinding aids, first introduced into cement manufacturing in 1930 [], are surface-active substances that facilitate particle comminution during the milling process.In the production of Portland cement, grinding aids are added in small amounts in the range of 0.01 to 0.10% by weight of cement, according to the PN-EN 197-1 standard [].They allow The Effect of Various Grinding Aids on the Properties of Cement

The Effect of Various Grinding Aids on the Properties of Cement
Surely, the factor which influences the efficiency of the superplasticizer is the adsorption of grinding aids on the surface of cement particles. Sun et al. showed that the decrease in surface energy, caused by the adhesion of glycerin used as a grinding aid, reduces the adsorption capacity of a PCE superplasticizer. Further work is needed inThe average particle diameter of cement was reduced by 3.65 μm when 0.03 wt% of PC was added as grinding aid. Moreover, high initial fluidity of the cement paste, 290 mm, could be reached when 0.08 wt% of PC was added. The fluidity loss of cement paste after 60 min and 90 min was 265 mm and 260 mm, respectively.Effect of Polycarboxylic Grinding Aid on Cement Chemistry
