Regarding addition of dry Fly Ash in Cement grinding process .
In my experience, dry flyash is normally added to the cement as it enters the cooler (to ensure adequate mixing). This is the cheapest option, however co-grinding of the flyash in the cement mill is becoming increasingly popular due to the mechanical 'activation' of the flyash, which allows for a higher.

Mechanochemical activation of aluminum: 1. Joint grinding of .
Mar 26, 2004 . It was shown that, at absorbed energy doses of 8–10 kJ/g, the grinding and mixing of aluminum with graphite is completed by the formation of an intermediate structure of Al/C composite, where aluminum showed an anomalously high reactivity. The interaction of aluminum with water was used to study its.
Self-Combustion Reactions Induced by Mechanical Activation .
The powders of aluminum metal and natural graphite mixed in various molar ratios (Al/C = 7/0–0/7) were ground in a planetary ball mill. When the mixtures thus activated mechanically were exposed to air, exothermic reactions spontaneously occurred in two successive steps, evolving red heat initially and then white heat.
