cement grinding aid mechanism
Comprehensive understanding of grinding aids
the industrial grinding of cement, even without the use of grinding aids. Therefore it can be assumed that the surfaces of the majority of commercial clinkers are predominantly or even completely hy - droxylated. This is also important because it as-sists the grinding, in other words water is a weak grinding aid. The chemical reaction of oxide ions

Cement Clinker Grinding Aids
Jul 12, 2016 Figure 4-26 shows a typical comparison between the grinding of cement clinker with and without a grinding aid. Grachyan and Tavlinova (1973) report that 0.1% of dior tri-ethanolamine increases the rate of clinker grinding by 22-29X, with glycerol and lower alcohols being less effective.
