re 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 percentage of flyash to be used in the cement.
