Regarding addition of dry Fly Ash in Cement grinding process
re Regarding addition of dry Fly Ash in Cement grinding process. Hello Rajuram, 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

Value in Waste: Fly Ash Reuse and Recovery Opportunities
One of the primary targets for recovery from fly ash has been alumina; most fly ash contains between 25 – 30% aluminum oxide (Al 2 O 3)¹. Some sources of fly ash in China have been shown to contain as much as 45% alumina. ² In addition to its use in producing aluminum metal, alumina is used throughout a host of industries as a catalyst
