Mechanical Activation of Fly Ash by High Energy Planetary

In this study fly ash was mechanically activated by high energy planetary ball mill for 1 hour at different speed ranging from 100 to 350 rpm and with varied ball to powder ratio 2:1 3:1 and 4:1 . The effects towards its particle size specific surface area and morphology were determined by particle size analyzer and SEM.

Coal/Coke/Fly Ash Union Process
