Can a vertical roller mill be used for grinding fly ash?

Fly ash is not easy to grind when entering the mill, because it is already ash, it will fly with the wind when it enters the mill and will not form a material layer at the bottom of the vertical mill. Other mixtures need to be added for grinding. After ash is processed, it is more common to be used as cement admixture, so the type of choice is usually cement raw material vertical mill.

What Is The Fineness Standard Of Secondary Fly Ash?
