Comparative Study On The Characteristics Of Ball

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 ...
