Coarse Fly Ash - an overview | ScienceDirect Topics
J. Jow, in Coal Combustion Products (CCP's), 2017 10.6.2 Milling or grinding. Milling or grinding can reduce coarse fly ash particles to fine particle size in a similar range as particles separated out from air classification. But milling does not directly compete with air classification, as milling is not a filtration technique.
