Dec 10 2015 High-energy mill HEM has a wide application in material preparation activation and synthesis. In the present study fly ash was selected to be milled by HEM under the speed of 700 rpm and the ball-to-powder ratio of 10:1 by weight but varied periods of milling time. The changes in physical and morphology properties of the milled fly ash were determined using BET analysis and scanning ...
